What is Sodium bicarbonate: Definition and 13 Discussions

Sodium bicarbonate (IUPAC name: sodium hydrogen carbonate), commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO3. It is a salt composed of a sodium cation (Na+) and a bicarbonate anion (HCO3−). 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.

    Can glucose combine with sodium bicarbonate?

    I fell upon an article outlining the general health benefits of a balanced pH, and specific anti cancer benefits. ... both concepts are well supported in published studies. The article then went on to describe a protocol, whereby sodium bicarbonate is dissolved in liquefied honey. The principal...

    Does sodium bicarbonate solution release CO2 when heated?

    Homework Statement Solid sodium bicarbonate decompose when it's heated above 50 celsius. However, when it is dissolved in water interactions of components changes. So what happens when sodium hydrogen carbonate solution is heated? Does it release carbon dioxide when temperature is above 50...

    Alka seltzer in water question

    Hi everyone. I was testing the pH of water that had alka seltzer placed in it. I used Bromothymol blue indicator to see the pH. The color changed to yellow, which suggests that the water was now acidic. I assume this is because of the CO2 bubbles that form which can acidify the H2O. Am I...

    Sodium bicarbonate and Acid Neutralization time

    If let's say a person accidentally has acid spilled in his hands, if he sprays or reaches for baking soda (or sodium bicarbonate) to neutralize the acd, how fast is the reaction? is it enough to avoid any skin damage? Are these part of any First Aid kit? Just curious about this. I read...

    Should sodium lipoate react with ascorbic acid?

    Hi, I've bought R-Alpha lipoic acid powder (not sure about its purity). So I mixed 500mg of ALA with 250mg sodium bicarbonate to get sodium lipoate, 30 minutes later (when the reaction is over) I added some 250mg of pure ascorbic acid to the final mixture and some small amount of insoluble...

    Ndicator of excess of sodium bicarbonate (HELP)?

    Homework Statement In a lab, i reacted NaHCO3 with HCl and put it under a steady flame and the reaction boiled. 1. What would indicate an excess of sodium bicarbonate instead of excess acid? is it precipitate? 2. Why was it necessary to add excess acid in the experiment? Is it so the NaHCO3...

    Does sodium bicarbonate function as an acid or a base?

    We conducted a lab on Friday and today we have to answer a few post lab questions. I'm stuck on one question and it asks: Does sodium bicarbonate (aka Baking Soda) (NaHCO3) function as an acid or a base? What sort of condition will determine this? I know that sodium bicarbonate will...
