Dear Singh

Basicity of H3PO4 is 3. as it is clear from the definition of basicity. Basicity of an acid refers to the number of replaceable hydrogen atoms in one molecule of the acid

H3PO4(aq) –> 3H+(aq) + PO4 3-(aq)


All the best.

Current 10 amp passed througj cuso4 for 32min 10 sec.if 896ml oxy liberated at stp calculate efficiency of cell
from faraday’s law, moles x valence factor = i*t/F moles = i*t/F*n = 10*1930/2*96485 = 0.100 approx. Moles given at STP = 0.896/22.4 = 0.04 efficiency = (0.1-0.04)/0.1 * 100 => 60%
