Textbook exercise J.7 states:
"Select an acid and a base for a neutralization reaction that results in the formation of (a) potassium bromide; (b) zinc nitrite; (c) calcium cyanide, Ca(CN)2; (d) potassium phosphate. Write the balanced equation for each reaction."
For part B, the answer is:
2HNO2(aq) + Zn(OH)2(aq) → Zn(NO2)2(aq) + 2H2O(aq)
Why is water formed in this neutralization reaction? In the textbook, it states that water is only produced if the base is strong. In this exercise, HNO2 is a weak acid and Zn(OH)2 is a weak base, so the intact acid/base molecules are the dominant species in solution.

Re: Neutralization Reaction (Textbook Exercise J.7B)
Neutralization reactions are ones where the reactants are an acid and base, and then the products are a salt and water.
