Which of the following statements regarding boric acid is false -

Options

  1. AIt acts as a tribasic acid
  2. BIt has a planar structure
  3. CIt acts as a monobasic acid
  4. DIt is soluble in hot water

Correct answer

A. It acts as a tribasic acid

Step-by-step solution

A Boric acid H 3 B O 3 is a lewis acid,when it is dissolved in water, it accepts O H - from water rather than donating H + to the water. So, A it is false. B It has a planar structure. C It acts as a monobasic acid: B ( OH ⁡ ) 3 + H 2 O → B ( OH ⁡ ) 4 - + H + D It is soluble in hot water.
