NaCl is a salt of strong acid (HCl) and a strong base (NaOH).Therefore, its solution is neutral with
pH = 7
CuSO4 is a salt of strong acid (H2SO4) and weak base [CU(OH)2]. Therefore, its solution is acidic with pH <7.
Na2CO3 is a salt of strong base (NaOH) and weak acid (H2CO3). Therefore, its solution is basic with pH >7.

Answer:( 1 ) NaCl is a salt of strong acid and strong base. Therefore, it's solution is neutral with pH = 7
( 2 ) CuSO4 is a salt of strong acid ( H2SO4 ) and weak base ( CuO ). Hence, it's solution is acidic with pH < 7
( 3 ) Na2CO3 is a salt of strong base ( NaOH ) and weak acid ( H2CO3 ). Hence, it's solution is basic with pH > 7.
