4 b) At pH 1.58, calculate the free [PO43-] when [PO43-]t = 22 mM. You can either solve 4 simultaneous equations to solve this problem for [H3PO4], [H2PO4-], [HPO42-] and [PO43-], or simply calculate the ratio of the two highest concentration species at the pH of the solution, and then calculate [PO43-] from those values. What are the two highest concentration species at pH 1.58?

Demonstrate that step 8 of the example in basic solution is balanced with respect to both mass and charge. That is, for mass balance, show that the number of each type of atom is the same on the reactant and product side, and for charge balance, show that the total charge of all species is the same on the reactant and product side.
I need help with these, I feel getting H+ and H2O as part of my final equation but always get marked wrong which doesn't make sense to me since an acid solution should have H+ as part of the final equation, no?
