Question
Given the following information:
(1) Write the net ionic equation for the reaction that occurs when equal volumes of 0.278 M aqueous nitrous acid andsodium acetate are mixed. It is not necessary to include states such as (aq) or (s).
______+_______------->_______+________
(2) At equilibrium the ________ will be favored.
A. reactants
B. products
(3) The pH of the resulting solution will be_______seven.
A. greater than
B. equal to
C. less than
nitrous acid HNO2 Ka = 4.5×10-4 acetic acid CH3COOH Ka = 1.8×10-5Explanation / Answer
1) net ionic equation:
HNO2 + CH3COO- -------------------> CH3COOH + NO2-
2)
equilibrium favoured : B. products
because HNO2 , Ka value is higher than acetic acid Ka value . so HNO2 is stronger acid and it can donate proton
3)
pH will more than 7
