2. Write the chemical equation for the reaction NaOH Sodium Hydroxide AgNO3 Silver Nitrate
lys-0071 [83]

Answer:

AgNO3 + NaOH = AgOH + NaNO3.

Explanation:

<em><u>Balancing Strategies: In this reaction, the products are initially NaNO3 + AgOH. However the AgOH would break down into Ag2O and H2O. This would give us NaNO3 + Ag2O + H2O as our products for the overall reaction.</u></em>
