Question

Select all the correct statements for a strong and weak acid.
A).A strong acid dissociates 100%
B).A weak acid dissociates less than 100%
C).A strong acid dissociates less than 100%
D).A weak acid dissociates 100%
E).A strong acid has a molarity greater than 1.0 M
F).An example of a weak acid is oxalic acid
G).An example of a strong acid is chlorous acid
H).A weak acid has a molarity less than 1.0 M

Answer 1

Explanation:

• Strong acid is the one that dissociates completely in water e.g. 100 %

• Due to complete dissociation , the hydrogen ion concentration is equal to the concentration of acid

• Morality of strong acids is greater than 1

Therefore, statements A, E are true for strong acid

• Weak acids dissociate less than 100 % in water

• Weak acids have morality less than 1

• Oxalic acid is an example of weal acid

Therefore, statement B, H, F are true for weak acids

Answer 2

Correct Statements for strog Acids are

A  And E

Any acid that dissociates 100% into ions is called a strong acid.

H2SO4 is a strong Acid.

A strong acid has a molarity greater than 1.0 M

Statement B, H, F are true for weak acids

If it does not dissociate 100%, it is a weak acid.

HC2H3O2 is an example of a weak acid:

An example of a weak acid is oxalic acid

A weak acid has a molarity less than 1.0 M
