Description

Sodium bicarbonate (IUPAC name: sodium hydrogen carbonate) is a chemical compound with the formula NaHCO3. It is a salt composed of sodium ions and bicarbonate ions. Sodium bicarbonate is a White solid that is crystalline but often appears as a fine powder. It has a slightly salty, alkaline taste resembling that of washing soda (sodium carbonate). The natural mineral form is nahcolite. It is a component of the mineral natron and is found dissolved in many mineral springs. It is among the food additives encoded by the European Union, identified as E 500. Since it has long been known and is widely used, the salt has many related names such as baking soda, bread soda, cooking soda, and bicarbonate of soda. In colloquial usage, the names sodium bicarbonate and bicarbonate of soda are often truncated. Forms such as sodium bicarb, bicarb soda, bicarbonate, bicarb, or even bica are common. The word saleratus, from Latin sal æratus meaning "aerated salt", was widely used in the 19th century for both sodium bicarbonate and potassium bicarbonate.The prefix "bi" in "bicarbonate" comes from an outdated naming system and is based on the observation that there is twice as much carbonate (CO3) per sodium in sodium bicarbonate (NaHCO3) as there is carbonate per sodium in sodium carbonate (Na2CO3) and other carbonates. The modern way of analyzing the situation based on the exact chemical composition (which was unknown when the name "sodium bicarbonate" was coined) says this the other way around: there is half as much sodium in NaHCO3 as in Na2CO3 (Na versus Na2).

Sodium Bicarbonate/Sodium Carbonate as Accelerator for Portland Cement

Yuli Wang, et al. Materials, 2019, 12(7), 1033.

Sodium bicarbonate (NaHCO3) and sodium carbonate (Na2CO3) can be used as accelerators to improve the rapid hardening ability and high early strength of concrete.
Effect of sodium bicarbonate/sodium carbonate on OPC
· The initial and final setting time of OPC paste decreased with the increase of either NaHCO3 or Na2CO3.
· The addition of either NaHCO3 or Na2CO3 could increase the early age compressive strength depending on the content added.
· As an accelerator, the addition 1% of either of the two accelerators could significantly shorten the setting time, increase the early age strength and did not have an obvious detrimental effect on the later age strength.
· Further increase of NaHCO3 and Na2CO3 above 1% could decrease the compressive strength of OPC paste although the ettringite formation was accelerated and increased.
· NaHCO3 was seen to be a better option as an accelerator compared to Na2CO3. The reaction between NaHCO3 and C3S was found to be much easier than the reaction between Na2CO3 and C3S.

Antimicrobial activity of sodium bicarbonate

Influence of plating medium, inoculum level, and incubation conditions (aerobic versus anaerobic) on the concentration of sodium bicarbonate reouired to inhibit bacterial growth

CORRAL, LAURA G., LAURIE S. POST, and THOMAS J. MONTVILLE. Journal of food science 53.3 (1988): 981-982.

Sodium bicarbonate (SB) inhibits the growth of bacteria and yeast in an agar medium model system under certain conditions. Escherichia coli, Lactobacillus plantarum, Staphylococcus aureus, and Pseudomonas aeruginosa counts were reduced by 10,000-fold by 0.12 M (1% wk) SB. Saccharomyces cerevisiae and Hansenula wenkelii were more sensitive at 0.06 M SB; counts were reduced by 100,000-fold. Potassium bicarbonate had the same inhibitory effect, but equimolar sodium chloride had no effect, ruling out osmotic and sodium-mediated mechanisms of inhibition. Bicarbonate ions have been suggested as a possible cause of SB-mediated inhibition, although in some cases, elevated pH played an important role.
Bacterial sensitivity to SB was tested in agar, a general medium for testing antimicrobial compounds, and in media appropriate for specific microorganisms. SB concentrations ranged from 0 to 6%. Media containing potassium bicarbonate (KB) and NaCl in molar amounts equivalent to Na + and HCO 3 were also prepared. Provided by inhibitory SB concentration. The media used as pH controls were adjusted to pH 10 using 5N NaOH. To examine the inhibition of bacteria in liquid systems, citrate phosphate buffers at pH 5.6, 6.0, 7.0 and Tris-HCl buffer at pH 8.6 were used. SB was added to each medium at 0 to 10% and the pH was readjusted with HCl. The control medium without SB was adjusted to pH 9.4 with 5N NaOH. All media were filter sterilized (0.45 pm) and used immediately.

Research on Sodium Bicarbonate for Swimming Performance

Descriptive data of the participants (n = 9)

Lindh, A. M., et al. International journal of sports medicine 29.06 (2008): 519-523.

Sodium bicarbonate ingestion has been shown to improve performance in single high-intensity events, possibly due to an increase in buffering capacity, but its effects on single bout swimming performance have not been investigated. The effects of sodium bicarbonate supplementation on 200 m freestyle performance in elite male athletes were investigated. Following a randomized, double-blind counterbalanced design, 9 swimmers completed maximal effort swimming on 3 separate occasions: a control trial (C); following sodium bicarbonate ingestion (SB: NaHCO3 00 mg/kg body weight); and following placebo ingestion (P: CaCO3 200 mg/kg body weight). SB and P agents were packaged in gelatin capsules and taken 90-60 min before each 200 m swim. Mean 200 m performance times were significantly faster with SB than with C or P. Base excess, pH, and blood bicarbonate were elevated before exercise with SB compared to C and P trials (p < 0.05). Blood lactate concentrations after 200 m were significantly higher after the SB test compared to the P and C (p < 0.05). It is concluded that SB supplementation can improve 200 m freestyle performance in elite male athletes, most likely by increasing buffering capacity.
For the SB and P tests, arterial capillary blood samples (90 μl) were collected sequentially at rest (before intake), after intake (55 min after completion of supplementation, i.e., 5 min before performance), and 3 min after performance for measurement of blood pH, base excess (BE), and bicarbonate concentration (HCO) using an iSTAT dry chemistry analyzer. These measurements using the i-STAT analyzer have been found to be reliable previously. In the control test, samples were collected at the post-intake and post-performance time points. To measure the blood lactate response to exercise, additional samples (50 μl) were collected at rest and then 1, 4, and 6 min after exercise and analyzed using a lactate analyzer. Blood lactate analysis using this analyzer has been reported to have high test-retest reliability (r = 0.99, CV < 3%). All blood samples were collected while the subjects were seated.

Amazing Results with Sodium Bicarbonate!
I recently used sodium bicarbonate in a dye conjugation reaction and I was amazed by the results! The buffer solution provided an ideal pH of 8.5 for the reaction, resulting in excellent conjugation efficiency. The purity of the conjugated antibody was also top-notch, thanks to the easy purification process involving a G-50 spin column. Overall, sodium bicarbonate greatly enhanced the success of my experiment and I highly recommend it to anyone working with dye conjugation reactions.
