Question
Answer the following question.
Identify the acid and base which form sodium hydrogen carbonate. Write the chemical equation in support of your answer. State whether this compound is acidic, basic, or neutral. Also, write its pH value.
Solution
Sodium hydroxide(base) and hydrogen carbonate(acid) combine to form sodium hydrogen carbonate.
\[\ce{2NaOH + H2CO3 -> Na2CO3 + 2H2O}\]
Sodium hydrogen carbonate is a basic salt because NaOH is a strong base and H2CO3 is a weak acid.
pH value of sodium hydrogen carbonate is 8.27.
