Question

What is the ph of sodium bicarbonate?

Answer 1

it should be more than 7

Answer 2

im doing research on why sodium bicarbonate absorbs ordors
do you know how i could calculate the ph level?
do you have an idea of how or what type of data i could collect?

Answer 3

Sodium bicarbonate is an amphoteric compound. It has a pKa of 6.3 in water which causes aqueous solutions to be mildly alkaline:

\[HCO _{3} ^{(-)} + H _{2} O → H ^{2} CO _{3} + OH ^{(-)} \]
The pH slightly above 7.0

The advantage of sodium bicarbonate is that it is amphoteric, hence reacts with acids and bases.
The reaction of acids with sodium bicarbonate is a common method for neutralizing acid and base spills.
For example,
with sulphuric acid:

2 NaHCO3 + H2SO4 → Na2SO4 + 2 H2O + 2 CO2

With sodium hydroxide:

NaHCO3 + NaOH → Na2CO3 + H2O
