Question

Which of the following Ką values represents the weakest acid?OA. K₂ = 1.82 x 10-1OB. K₂= 3.24 × 10-7OC. K₂ = 1.29 × 10-4Ka=OD. K₂ = 1.62 × 10-12

Answer 1

OD. Ka = 1.62 × 10-12

Step-by-step explanation:

An acid is weak the smaller the Ka value, so the weakest acid in this case is the one with a Ka=1.62 × 10-12.
