Equilibrium, Charge Balance, Mass Balance

  1. Aug 22, 2013 #1
    1. The problem statement, all variables and given/known data

    Write the charge balance for a solution containing H(+), OH(-), Ca^(2+). HCO3(-). CO3^(2-) , Ca(HCO3)+, Ca(OH)+, K+, and CIO4(-).


    2. Relevant equations

    Also, I am having a trouble understanding the concepts of mass balance and charge balance.

    3. The attempt at a solution

    The only thing I know to do is put the positive charges on one side and the negatives on the other, and then change the coefficients.

    you need a balanced chemical reaction equation

    Do it then.

    Charge balance means just that the solution is electrically neutral - sum of all negative charges equals sum of all positive charges.

    No. Reaction equation can help in writing mass balance, but even that is not required.
