Question

100g HCL (C=25%) + Ca(OH)2 (C=25%)
a) ms (Ca(OH)2) = ?
b) Cfinal = ?

Answer 1

C=md/ms*100=>md=25g HCl

2*36,5g.....74g...........111g......2*18g
2HCl + Ca(OH)2 => CaCl2 + 2H2O
25g......x=25,342g.......y=38g.....z=12,32876g

C=md/ms*100 => ms=md*100/C=25,342*100/25=101,37g sol. Ca(OH)2

md final = 25,342+38+25=88,342g

ms final =100+25,342+38+12,32876=175,67g

C final =mdf/msf*100=88,342/175,67*100=50,288%

nu sunt sigur..
