Final answer:
When dissolved in water, NaNO3 will have a pH greater than 7.
Step-by-step explanation:
A solution with a pH greater than 7 is considered basic. One of the ways to determine the pH of a solution is by looking at the ions it produces when dissolved in water. When a compound dissociates in water, it forms ions that can either be acidic or basic. In this case, when dissolved in water, the compound that will have a pH greater than 7 is option d) NaNO3. Sodium nitrate (NaNO3) dissociates into Na+ and NO3- ions. Both of these ions are neutral and do not contribute to the acidity or basicity of the solution. Therefore, the resulting solution will have a pH greater than 7, making it basic.
