Question

Choose the correct option :
$H_{3}P{O}_4$ is a _________ acid,
$H_{3}P{O}_3$ is a _________ acid and
$H_{3}P{O}_2$ is a _________ acid.

• A. dibasic, tribasic, monobasic
• B. tribasic, monobasic, dibasic
• C. monobasic, dibasic, tribasic
• D. tribasic, dibasic, monobasic

Answer 1

The correct option is D tribasic, dibasic, monobasic

From figure it can be seen that,

$H_{3}P{O}_4$ is a tribasic acid,

$H_{3}P{O}_3$ is a diabasic acid and

$H_{3}P{O}_2$ is a monobasic acid.
