Question

calculate equivalent mass of h2po3​

Answer 1

Answer:

Explanation:

The equivalent weight defined as the quantity that combines with or replaces 1.00797 grams (g) of hydrogen or 7.9997 g of oxygen; or, the weight of an element that is liberated in an electrolysis.The equivalent weight of H2PO3- is when H2po3- reacts with 1 mole of NaOH then its equivalent weight will be molecular mass/1 (n factor=1) but if it reacts with 2 moles of NaOH then its equivalent weight will be molecular mass/2 (n factor=2)
