Explanation Given: 0.01 M in HCl and 0.01 M KOH 0.01 M HF and 0.01 M in KBr 0.01 M NH 4 Cl and 0.01 M CH 3 NHBr 0.1 M NaCN and 0.1 M CaCl 2 According to Arrhenius acid and base concept, a substance that can easily dissociates in water and released H + ions is known as acid and as the number of H + ions increases the acidic strength of that substance increases. Similarly, a substance that can easily dissociates in water and released OH - ions is known as base and as the number of OH - ions increases the basic strength of that substance increases. There is another concept for acid-base that given by Lewis according to that an acid can accepts lone pair of electrons and a base can donate its lone pair of electrons. On the basis of above two concepts, we can find out which substance will be more acidic in given pairs. Given pairs dissociates in water as: a. HCl + H 2 O ⇌ H + (aq) + Cl - (aq) KOH + H 2 O ⇌ K + (aq) + OH - (aq) From above reaction it is clear that KOH gives OH - ions therefore, it will be basic and HCl gives H + therefore HCl will be acidic. b. HF + H 2 O ⇌ H + (aq) + F - (aq) KBr + H 2 O ⇌ K + (aq) + Br - (aq) From above reaction it is clear that HF gives H + ion it means HF will be more acidic...

Ionic Equilibrium

Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibri…

Arrhenius Acid

Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
