Question

In the equation HI + H2O → H30* + I-, HI is a strong acid and I is a
on
Select one:
O a. strong acid.
O b. strong base.
O C. weak acid.
O d. weak base.

Answer 1

I⁻ acts a strong base.

Explanation:

HI + H₂O → H₃O⁺ + I⁻

• HI acts as a strong acid, by means of donating a proton to the water there by forming hydronium ion (H₃O⁺), formed by the addition of H⁺ with H₂O.

• I⁻ accepts H⁺ ion, there by forming HI in the reverse reaction, so it is a strong base. Any substance which accepts H⁺ ion acts as a strong base.

• So in the above equation I⁻ is a strong base.
