How do you balance these equations?

Question

Al(OH)3 + H2SO4

NaOH+ H3PO4

Answer 1

First write your products - these are acid-base reactions and will form water and a salt (the first part of the base combines with the last part of the acid).

Use the charges of the elements and radicals to write the correct subscripts on the products.

Use coefficients to balance the reactant and product atoms.

2Al(OH)3 + 3H2SO4 = Al2(SO4)3 + 6H2O

3NaOH + H3PO4 = Na3PO4 + 3H2O
