Question

[07.02]what is the concentration of a ca(oh)2 solution if 10.0 ml of 0.600 m h3po4 solution is required to completely neutralize 12.5 ml of the ca(oh)2 solution? 0.320 m 0.480 m 0.720 m 1.44 m

Answer 1

In neutralization process or titration process, we use the formula;
(M1V1)H3PO4 = M2V2(Ca(OH)2)
M1 = 0.600 m
V1 = 10.0ml
M2 = unknown
V2 = 12.5ml
M1V1 = M2V2
0.6*10 = 12.5*M2
M2 = (0.6*10)/12.5 = 0.48m
Therefore, the answer is 0.480m
