Question

identify which ion is a spectator ion in the following acid-base reaction: 2 hclo4 ca(oh)2 → ca(clo4)2 2 h2o.

Answer 1

The spectator ions in the given acid base reaction are Ca^2+(aq) and ClO4-(aq). The net ionic equation can be formed by removing these spectator ions.

Step-by-step explanation:

A spectator ion is an ion that does not take part in the chemical reaction and is found in solution both before and after the reaction. In the given acid-base reaction:

2 HClO4(aq) + Ca(OH)2(aq) → Ca(ClO4)2(aq) + 2 H2O(l)

The spectator ions are Ca2+(aq) and ClO4-(aq). They do not participate in the reaction and can be removed to form the net ionic equation:

2 H+(aq) + 2 OH-(aq) → 2 H2O(l)

Answer 2

Ca and ClO4

Calcium hydroxide is a strong base
Perchloric acid is a strong acid

Calcium and perchlorate are the spectator ions because they have no effect on an acid base rxn.
