periodic table, which list
shows the acids in order from
strongest to weakest?
(1 point)
HCl, PH3
, H2S
HCl, H2S, PH3
H S, PH , HCl 2 3
PH , H S, HCl

Answer 1

To determine the strength of the acids listed, we can consider the properties of the compounds:

1. HCl (Hydrochloric acid): This is a strong acid that completely dissociates in water.

2. H2S (Hydrogen sulfide): This is a weak acid. It does not fully dissociate in water and is much weaker than HCl.

3. PH3 (Phosphine): This compound does not typically act as an acid in aqueous solution and is much weaker than both HCl and H2S.

Based on this information, the order from strongest to weakest acid is:

HCl, H2S, PH3

So the correct answer is:

HCl, H2S, PH3.
