A buffer is prepared by adding 7.00 g of ammonia (NH3) and 20.0 g of ammonium chloride (NH4Cl) to enough water to form 2.50 L of solution. (a) What is the pH of this buffer? (b) Write the complete ionic equation for the reaction that occurs when a few drops of nitric acid are added to the buffer. (c) Write the complete ionic equation for the reaction that occurs when a few drops of potassium hydroxide solution are added to the buffer.
