Ionization of HCl is given below: HCl + HOH -----------> Cl- + H3O+ label the two conjugate acid- base pairs in the ionization.

(d) : HSO3 F is the super acid. Its acidic strength is greater than any given species. The pKa value of other species are given below : HCO3– →10.25 H3 O+ →...

pyramidal....

Conjugate acid is H2CO3 a conjugate acid is CO3 2- 

HCl + HOH -------->  Cl- + H3O+  CH3COOH + HOH -------->  CH3COO- + H3O+  HCl is strong acid but chloride ion is a weak base similarly CH3COOH is weak acid but CH3COO-...

These differ from each other by proton. Acid ----------> Conjugate base + proton  Base ------------> Conjugate acid+ proton

Ka x Kb =Kw  Kb= Kw/Ka  =1 x10-14/1.8x10-8  =5.55x10-7

(b) Formic acid is stronger than acetic acid due to its chemical composition. Formic acid is an organic acid as well as active acid in an organic acid.

Three are three O-H bond pairs and one lone pair on oxygen atom in H3O+ ion so the ion has pyramidal shape. 

If (A) is correct but (R) is wrong

These solutions can be tested by using universal indicators. If the solution (i) turns red it is an acid and If the solution (ii) remains colourless it is a base.
