Answer to Question #154971 in Chemical Engineering for Mohammedazeem Rokad

Question

A stream of aqueous sulphuric acid of 62.4 wt% H₂SO₄ is mixed with pure water in a stirred vessel to produce a stream of 20.5 wt% acid. What ratio of water to concentrated acid should be used?

Answer 1

62.4 - 20.5 = 21.9 ml

0 - 20.5 = 20.5 ml

To get 20.5 wt% solution we need 21.9 ml of 62.4 wt% H₂SO₄ solution and 20.5 ml of H₂O.
