If salt is dissolved in pure water, it's pH remains same then salt is :
(1) `CH_(3) COONa`
(2) NaCl
(3) `Na_(3)PO_(4)`
(4) `(NH_(4))_(2)SO_(4)`

Count the number of pairs which may act as a buffer solution when present in a given solution (a) CH_(3)COOH +NaOH (b) (c) NH_(4)CI + HNO_(3) (d) HCIO_(4) +KCIO_(4) (e) H_(3)PO_(4)+NaOH (f) H_(3)PO_(3) +NaOH (g) NaHCO_(3) + Na_(2)CO_(3) (h) H_(2)SO_(4) + Na_(2)SO_(4) (i) CH_(3) COONa + HCI (j)

Write the cations and anions present (if any) in the following compounds? a) CH_(3)COONa b) NaCl c) H_(2) d) NH_(4)NO_(3)

Determine the equivalent weights of the following salts: (a) NaCl" " (b) K_(2)SO_(4) " " Ca_(3)(PO_(4))_(2)

FeCl_(3)+Na_(3)PO_(4) to FePO_(4)darr+3NaCl

3AgNO_(3)+Na_(3)PO_(4) to Ag_(3)PO_(4) darr+3NaNO_(3)

Na_(3)PO_(4)+Fe_(2)(SO_(4))_(3) to FePO_(4) darr+Na_(2)SO_(4)
