Question
Given the following information:
(1) Write the net ionic equation for the reaction that occurs when equal volumes of 0.366 M aqueous hydrocyanic acid and sodium acetate are mixed. It is not necessary to include states such as (aq) or (s).
(2) At equilibrium the _________reactantsproducts will be favored.
(3) The pH of the resulting solution will be _________greater thanequal toless than seven.
Image is not needed it is just where you input your answer
hydrocyanic acid HCN Ka = 4.0×10-10 acetic acid CH3COOH Ka = 1.8×10-5Explanation / Answer
1)
net ionic equation:
HCN (aq ) + CH3COO- (aq) ------------------------> CH3COOH (aq) + CN- (aq)
CH3COOH is stronger acid than HCN.
so reverse reaction will be favourable
2)
at equilibrium reactatns are favoured
3)
pH of soultion should be greater than 7
because CN- involve in hydrolysis process . and OH- will be produced
CN- + H2O ---------------------> HCN + OH-
