Question

In water, or aqueous solutions of HCl or H2SO4, proton exists as:
  1. H3O+
  2. H(H2O)+n
  3. all correct
  4. H(H2O)+4

A
H3O+
B
H(H2O)+n
C
all correct
D
H(H2O)+4
Solution
Verified by Toppr

In water, or aqueous solutions of HCl or H2SO4, proton exists as either H3O+ or H(H2O)+2 or H(H2O)+3.

Thus, proton does not exist as free proton H+ but it is solvated with one, two or three molecules of water.

Option D is correct.

Assertion :It is difficult to distinguish the strengths of the strong acids such as HCl, H2SO4,HNO3 HBr, HI or HClO4 in dilute aqueous solutions. Reason: In dilute aqueous solution all strong acids donate a proton to water and are essentially 100% ionised to produce a solution containing H3O+ ions plus the anions of strong acid.
