In a binary solution, the component present in smaller proportion is called solute while the one in excess is known as solvent. The solution containing 1 mole of the solute in 1L of solution is known as one molar solution while the solution in which 1 mole of solute is dissolved in 1 kg of the solvent is called one molal solution. The ratio of the no. of moles of a particular component to the total no. of moles in the solution is known as its mole fraciton
1.57 g of oxalic acid `(COOH)_(2)xH_(2)O` are dissolved in water and the volume is made upto 250 mL. On titrating 6.68 mL of this solution requires 25 mL of N/15 NaOH solution for complete neutralisation. The value of x is :

A

3

B

2

C

Text Solution

Verified by Experts

The correct Answer is:
B
Normality fo oxalic acid may be calculated as :
`N_(1)V_(1)-=N_(2)V_(2)`
`N_(1) xx16.68=1//15xx25`
`N_(1)=(25)/(15xx16.68)=0.1N`
Eq. mass of oxalic acid `= ("Strength")/("Normality")`
Molecular mass of oxalic acid `= 63 xx2= 126`
On comparison,
`90 + 18x = 126 or x=2`.
