Question

Explain why? Acid like hcl, h2so4, and hclo4, will have equal strengths in water.

Answer 1

Answer:

The statement that the acids HBr and H2SO4 have equal — or, more accurately, near equal — strengths in water (by which is meant the degree of dissociation into H+ and the other component ion, Br− and (HSO4)− , respectively) is most accurate when the two are considered for equal Molar/molal concentrations. As a side note, at very dilute concentrations, one may invoke the assumption below:

Molarity,M ≃ molality,m
