what is the difference between Hydrolysis and Electrolysis.??

Dear Student,
Hydrolysis - It is the reaction that involves the cleavage of bond or decomposition of the substance using water. The water molecule gets split into cation(H⁺) and anion(OH^-). They attack on the bond and split the substrate into fragments.
Hydrolysis reaction can be carried upon the solid or liquid substrates ,also the hydrolysis can be acidic or basic.
Example - hydrolysis of esters or salts . Hydrolysis of acids or bases. Both ionic and covalent can undergo hydrolysis.
Hydrolysis also takes place in biological cells (breakdown of food during digestion)
$$\begin{gathered} NaCl+H_{2}O\to NaOH +HCl \\ C{H}_{3}COONa+ H_{2}O\to NaOH +C{H}_{3}COOH \\ C{H}_{3}COOC{H}_{2}C{H}_3+H_{2}O\rightleftharpoons C{H}_{3}COOH +C_2{H}_{5}OH \end{gathered}$$
Electrolysis- Electrolysis is a process that involves a chemical change by passing electric current through a substance in aqueous,fused and molten state. The chemical change involves loss or gain of elctrons. (oxidation or reduction of electrolyte) .Substances that are ionic mostly undergo electrolysis. Electrolysis also takes place in biological cells (electron transport chain during respiration).
Example : electrolysis of  molten NaCl
$$\begin{gathered} NaCl\left(molten\right)\to N{a}^{+}+C{l}^{-} \\ At cathode : N{a}^{+}+e^{-}\to Na\left(s\right) \\ At anode : C{l}^{-}\to Cl+e^{-} \\ Cl+Cl\to C{l}_2\left(g\right) \end{gathered}$$
The electrolytic products of aqueous NaCl will be different .(H₂ gas at cathode and O₂ gas at anode)
​Regards!
