Reactions in a buffer solution

When an acid or a base is added to a buffer, a double-displacement reaction will occur. The acid or base will be neutralized, forming a neutral salt or water plus the conjugate of the buffer. For example, if the base NaOH is added to a buffer containing HCN and NaCN, the base will react with the acid HCN as shown:

NaOH(aq) + HCN(aq) → NaCN(aq) + H2O(l) 

Complete the following chemical equations to show what happens when HBr or KOH is added to a buffer solution made from HF and KF 

Part B

Identify the reaction that occurs when the acid HBr is added to the buffer solution 

Drag each label to the appropriate target. 

Part C 

Identify the reaction that occurs when the base KOH is added to the buffer solution. 

Drag each label to the appropriate target.
