solutie 1: Vs1 cM1= 10⁻³ mol/l n1HO⁻ = 10⁻³ₓVs1
solutie 2 : Vs2 cM2 = 10⁻¹ mol/l n2HO⁻ = 10⁻¹ₓVs2
------------------------------------------------------------------------
solutie finala : Vs = Vs1 + Vs2 pH = 12 pOH = 2 [HO⁻] = 10⁻² = cM finala
(10⁻³ₓVs1 + 10⁻¹ₓVs2) /(Vs1+ Vs2) = 10⁻² | :10⁻²
0,1Vs1 + 10Vs2 = Vs1 + Vs2
0,9Vs1 = 9Vs2 Vs1/Vs2 = 10/1
