Answer 1

Answer #1

NaNO3 is neutral solution PH = 7 because of it is salt of strong acid(HNO3) and strong base (NaOH)

NaNO3 solution PH = 7

Na2CO3 solution is basic nature PH >7 because of it is salt of weak acid (H2CO3) and strong base ( NaOH)

Na2Co3 solution PH is greater than 7

NH4Cl solution is acidic nature. PH<7 because of it is salt of strong acid (HCl) and weak base ( NH3)

NH4Cl solution PH is less than 7

NaHSO4 is neutral solution PH = 7 because of it is salt of strong acid(H2SO4) and strong base (NaOH)

NaHSO4 solution PH = 7

Na2SO4 is neutral solution PH = 7 because of it is salt of strong acid(H2SO4) and strong base (NaOH)

Na2SO4 solution PH = 7
