kompoz [17]

Answer:

A)true

B)false

C)true

D)false

E)false

Explanation:

Step 1: Data given

Volume = 1.00 L

Number of moles HCN = 0.49 moles

Number of moles NaCN = 0.38 moles

Number of moles HCl added = 0.19 moles

Step 2:

This is a buffer system consisting of a weak acid, HCN and the salt of that acid, NaCN.

Upon addition of hydrochloric acid (HCl), HCN is formed and NaCl is used up.

HCl + NaCN ⇔ NaCl + HCN

A. The number of moles of HCN will increase. This is true.

B. The number of moles of CN- will increase.

⇒ false, The number of moles of CN- will decrease b/c it is now part of HCN, a weak acid.

C. The equilibrium concentration of H3O will increase.  

 ⇒ True, The [H3O+] will increase slightly.

D. The pH will increase.

⇒ False, The pH will decrease slightly because acid is being added and being converted to HCN

E. The ratio of [HCN] / [CN-] will remain the same.

⇒ False. It will increase.
