Not sure how to complete parts b and c

A buffer is prepared by adding 9.00g of ammonia (NH3) and 22.0g of ammonium chloride (NH4Cl) to enough water to form 2.50 L of solution. What is the pH of this buffer? Write the complete ionic equation for the reaction that occurs when a few drops of nitric acid are added to the buffer. Express your answer as a chemical equation. Identify all of the phases in your answer. Write the complete ionic equation for the reaction that occurs when a few drops of potassium hydroxide solution are added to the buffer. Express your answer as a chemical equation. Identify all of the phases in your answer.

Explanation / Answer

Complete ionic equations represent soluble ionic compounds as separated ions.
m thinking something like this,wid an example...
HNO3-(aq) + NH3(aq) + Cl-(aq) + OH-(aq) -> NH4Cl(aq) + NO3-(aq) + H2O(l)
or..
NH3(aq) + H+(aq) -> NH4+(aq)....

Similarly,,,for 2nd part...Its like this.

NH4+(aq) + OH-(aq) -> NH3(aq) + H2O(l)
