Question 13.10: Write an equation to explain why NO2^-, Na2CO3, and KHCO3 pr...

Chemistry: Principles and Reactions

Write an equation to explain why ${NO_2}^-$ , $Na_2CO_3$ , and $KHCO_3$ produce basic water solutions.

STRATEGY

1. React each basic anion with a water molecule.
2. The weak base picks up the proton $(H^+)$ and increases its charge by one unit to create its conjugate acid.
3. $OH^-$ is the other product of the reaction.
