Can anyone tell me what is in a pH 10 buffer tablet?

Question

What is in pH 10 buffer tablets/powder, and how do they work? I need to know within the next day if possible.

Thanks in advance

Answer 1

Mixture of Sodium bicarbonate and Sodium carbonate.

( NaHCO3  +  Na2CO3  Mixture )  

Buffer is a mixture of [ Weak Acid + Conjugate Base Salt ] or [ Weak Base + Conjucate Acid Salt ].  

Buffer will give best performance if the Acid - Base Pair have equal concentation  ( 1 : 1 ) .
