Answer:
H3PO4 + 3KOH---------> K3PO4 + 3H2O
Explanation
H3PO4 + KOH------------> K3PO4 + H20
when an hydrogen ion containing acid (HX) reacts with a hydroxide containing base(BOH) they produce water and a "salt".
water can be called dihydrogen oxide (H2O), but it can also be called
hydrogen hydroxide (HOH)...same thing.
so the phosphoric acid (H3PO4) contains 3 hydrogen ions (H), and needs 3
hydroxide ions to from 3 hydrogen hydroxides .. that is 3 waters AND A "SALT" WITH THE REMAINING SPECIES ( K AND PO4)
so let us balance
H3PO4 + 3KOH--------->K3PO4 + 3HOH or
H3PO4 + 3KOH---------> K3PO4 + 3H2O
Check:
6 H on the left side, 6 H on the right side
1 P on the left side, 1 P on the right side
3 K on the left side, 3 K on the right side
7 O on the left side, 7 O on the right side
abadabaabdabadaba........that's all folks
yup it is balanced
