Answer 2

$\huge\mathfrak\red{Answer :}$


$\huge\textbf{Soap :}$


It is the Na or K salt of higher fatty acids... such as stearic acid, palmitic acid, oelic acid. When hard water is treated with soap, then ${Can}^{2+}$ and ${Mg}^{2+}$ ions of hard water reacts with soap and forms scum or Curdy white precipitate instead of lather...

$C_{17}H_{35}CO{O}^{-}$${Na}^{+}$ + $CaCl_{2}$ ----> $(C_{17}H_{35}COO)_{2}Ca\:+\:2NaCl$
