9 Which of the following salts is acidic k Sodium oxalate Na
     9. Which of the following salts is acidic? k) Sodium oxalate (Na2C204) 1) Potassium chloride (KCI) m) Iron (IT) chloride (FeCh) n) Lithium carbonate (Li2CO) o) None of the above salts are acidic  
  
  Solution
Answer is option (m)
Na2C2O4 sodium oxalate => basic salt
Since it\'s formed from a strong base ( NaOH) and a weak acid ( H2C2O4).
KCl => neutral
Since it\'s formed from strong base ( KOH) and a strong acid (HCl).
FeCl2 => acidic
Since, it\'s formed from a weak base ( Fe(OH)2 ) and a strong acid ( HCl )
Li2CO3 => basic
Since it\'s formed from a strong base LiOH, and a weak acid H2CO3 .
