Answer
Strong acid - (b)
Weak acid - (c)
Very weak acid - (d)
Work Step by Step
(1) In a strong acid solution we should expect:
- HCl: Zero (Because all of it got ionizated).
- H+: Yes, a good quantity.
- Cl-: Yes, a good quantity.
The diagram that represents this is (b)
(2) In a weak acid solution we should expect:
- HCl: Yes. (Because they didn't got completely ionizated.)
- H+: Yes, because some part have ionizated.
- Cl-: Yes, because some part have ionizated.
- They all are in a moderated quantity.
The diagram that represents this is (c).
(3) In a very weak acid solution we should expect:
- HCl: In large quantities.
- Cl-: In low quantity.
-H+: In low quantity.
The diagram that represents this is (d).
