MCQ
Select the correct answer for the following multiple choice questions.
1. The molar mass of oxalic acid is .. .......
a. 126 u b. 126 g/Mol
c. 12.6 u d. 12.6 g/Mol
Answer. b. 126 g/Mol
Share this video with your friends.
2. To prepare 1 M solution of oxalic acid
a. 126 g of oxalic acid dissolve in distilled water and diluted to 1 L.
b. 12.6 g of oxalic acid dissolve in distilled water and diluted to 1 L.
c. 1.26 g of oxalic acid dissolve in distilled water and diluted to 1 L.
d. 0.126 g of oxalic acid dissolve in distilled water and diluted to 1 L.
Answer
a.126 g of oxalic acid dissolve in distilled water and diluted to 1 L.
3. Water of crystallization present in oxalic acid is/are .........
A. 1 b. 2 c. 3 d. 5
Answer
B. 2
4. Oxalic acid is used to prepare standard solutions because it
Short Answer Questions
1. Calculate the molar mass of oxalic acid
(H=1,C=12, O=16)
Answer
Molecular formula H2C2O4 2H2O
Motar mass : (2×1)+(2×12)+(4×16)+4×32
=126 g/Mol
2. Why heating is required in oxalic acid and potassium permanganate titration?
Answer
At room temperature the process is very slow thus to increase rate of reaction heating is required.
3. Why one test tube of 2M sulphuric acid is required in permanganatic manganese by forming manganese dioxide.
4. What is the oxidation state of carbon atom in oxalic acid after completion of redox titration?
Answer
the oxidation state of carbon atom in oxalic acid changes from +3 to +4.
5. Why primary standard solutions are used to make standard solutions?
Answer
Because,Primary standard solutions have high degree of purity and they are stable and unaffected by moisture.
