Homework Answers
Volume of Ca(OH)2 taken(V1) = 10 ml
Concentration of Ca+2 (M1)= ?
Volume of HCl required to neutralise(V2) = 4.86 ml
Concentration of HCl(M2)= 0.043M
Temperature condition = 20oC
Indicator = Bromothymol blue
At the end point
M1V1 = M2V2
M1 * 10 = 0.043 * 4.86
M1 = 0.0209 M
Initial concentration of Ca2+ = 0.0209M
