1.0 g of a monobasic acid when completely acted upon Mg gave 1.301 g of anhydrous Mg salt. Equivalent weight of acid is _________

Ew of acid Ew of salt of Mg= Weight of acid  Weight of salt Mg+2HCl (monobasic acid) →MgCl2+H2 Let Ew of acid =Ew of H+Ew of acid radical ∴Ew of salt of Mg=Ew of Mg+Ew of acid radical ∴Ew of acid Ew of Mg salt = Weight of acid  Weight of Mg salt ⇒Ew of H+Ew of acid radical (E)Ew of Mg+Ew of acid radical (E)=1.01.301⇒1+E12+E=1.01.301∴E=35.54∴Ew of acid =Ew of H+Ew of acid radical  =1+35.54=36.54
