the base is diprotic,
Na*Va=Nb*Vb
.0215Va=2*.0150*.235L
solve for Volume of the acid, Va
What volume (in mL) OF 0.0215M HBr solution is be required to titrate 0.235L of a 0.0150M Ca(OH)2 solution? Ca(OH)2+2HBr= CaBr2+2H2O

nM1V1=nM2V2
n= the moles from the balance equation
HBr Ca(oH)2
2(0.0215)V1=1(0.015)(0.235L)
V1= 0.08192L
