Aqueous solution of phosphoric acid with...

Aqueous solution of phosphoric acid with a density of `1 g mL^(-1)` containing 0.05% by weight of phosphoric acid is used to impart taste to many soft drinks.
What is the molarity of phosphoric acid used in soft drinks ?

A

`5.1 xx 10^(-3)`

B

`1.5 xx 10^(-3)`

C

`3.1 xx 10^(-3)`

D

`2.1 xx 10^(-3)`

Text Solution

Verified by Experts

The correct Answer is:
A
`(0.05)/(100) xx 1 xx (1000)/(98) = 5.1 xx 10^(-3)`

The dissociation of weak electrolyte (weak acid) is expressed in terms of Ostwald dilution law. Stronger is the acid, weaker is its conjugate base. The dissociation constants of an acid (K_(a)) and its conjugate base (K_(b)) are related by the given relation : K_(w) = K_(a) xx K_(b) At 25^(@)C, K_(w) (Ionic product of water ) = 10^(14) . Phosphoric acid is a weak acid. it is used in fertilizer, food, detergent and toothpaste.

There are two types of fertilisers F_1 and F_2, F_1 consists of 10% nitrogen and 6% phosphoric acid and F_2 consists of 5% nitrogen and 10% phosphoric acid.
