Answer:
0.80 M ion concentration
Explanation:
Step 1: Define
0.20 M solution of Na₃PO₄
Step 2: Find ions (Decomposition RxN)
Na₃PO₄ → 3Na⁺ + PO₄³⁻
Step 3: Find ion concentration
3Na⁺ - 3(0.20 M) = 0.6 M Na⁺ ion
PO₄³⁻ - 1(0.20 M) = 0.2 M PO₄³⁻ ion
Step 4: Add ion concentrations
0.6 M + 0.2 M = 0.80 M ion concentration
