Question

For a 0.1 M aqueous solution of sodium acetate, Na+ CH3COO- , one mass balance expression is simply [Na+ ] = 0.1 M. Write a second mass balance expression for this system. b. [5 pts] Write a charge balance expression for a solution containing H+ , OH- , Ca2+, HCO3 - , CO3 2- , Ca(HCO3) + , Ca(OH)+ , K+ and ClO4 - .

Answer 1

A) the ions in the solution are separated in equal number of ions so as they have the same concentration therefore there mass balance equation will be giving the same value for both ions.

B) Charge balancing has a general formula as stated below to maintain electrical neutrality in a bulk solution. All the ions in the solution contribute in the charge balance. This is represented by a charge balancing equation as given below.

I hope you understand the concept. Kindly give a feedback.
