Concept explainers
Arrange each of the following in order of increasing acidity. You may need to use a couple of rules to decide the order for a given series. Explain the reasoning you use in each case.
- a HBrO2, HBrO3, HBrO
- b H2TeO3, H2SO3, H2SeO3
- c HI, SbH3, H2Te
- d H2S, HBr, H2Se
- e HClO2, HClO3, HBrO2
(a)
Interpretation:
Each of the given set of acids, in the order of increasing acidity has to be arranged.
Concept introduction:
Acid:
According to Bronsted-Lowry theory, a species which donates a proton in a proton transfer-reaction is said to be an acid.
Base:
According to Bronsted-Lowry theory, a species which accepts a proton in a proton transfer-reaction is said to be base.
Strong acid:
According to Arrhenius theory, a compound or a substance which completely ionized in a aqueous solution to give a hydronium ion and anion is said to be strong acid.
Strong base:
According to Arrhenius theory, a compound or a substance which completely ionized in a aqueous solution to give a hydroxide ion and cation is said to be strong base.
