Question

64. Which of the followings can dissociate in water?

a. CH3COOH
b. CaCl₂
c. HCI
d. NH3

Answer 1

HCl

Step-by-step explanation:

The vant Hoff factor for dissociation is 2

See

`\\ \tt{:}\longrightarrow HCl\longrightarrow H^++Cl^-`

• HCl is known as one of very strong acids
• It can do 100% dissociation in water
• It releases hydronium ions

Answer 2

HCl

Step-by-step explanation:

Dissociation denotes to increase in mols

Vant Hoff factor for dissociation is always Greater than 1

Here the reaction is given by

• HCl—»H+ +Cl-
