What is the concentration of ALL ions in a 0.20 M solution of Na3PO4

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

b. examine and describe cells

c, liquids evaporate, creating a gas
