Another example of a common ion effect is CH 3 COOH and CH 3 COONa. Consider a weak electrolyte, CH 3 COOH, partially ionized and gives ions. CH 3 COOH ⇌ … WebAug 18, 2024 · For example, an oxygen atom starts with eight protons and eight electrons. It is given the symbol O. When it forms its most common ion, oxygen gains two electrons to become the “oxide anion.” Chemists denote this by adding a 2-minus on the upper right side (O 2-). That superscript tells you its charge. tithe collector ff14
