1 mole of NaOH contains 1 mole of hydroxide ions.
Hence, 1 equivalent of NaOH = 1 mole of NaOH
No. of equivalents of NaOH = No. of moles of NaOH = 0.0215
Equivalent weight of the acid = 1.237/0.0215 = 57.5
Hence, 1 equivalent of NaOH = 1 mole of NaOH
No. of equivalents of NaOH = No. of moles of NaOH = 0.0215
Equivalent weight of the acid = 1.237/0.0215 = 57.5
