Question

Which of the following will represent the normality of $10\%\left(w/V\right)$ acetic acid?

• A. $1.66$ N
• B. $16.6$ N
• C. $3.32$ N
• D. $33.2$ N

Answer 1

Answer: (A)

$1.66$ N

Weight by volume means the amount of solute present by 100ml of solution.

10% (w/v) acetic acid means that 10g of acetic acid is present in 100ml of solution.

Normality =number of gram equivalents of solute/volume of solution (in litres)

$N=\frac{10/60}{100}\times 1000eq{L}^{-1}$

$=1.66$N

Hence, the correct option is $A$
