If 1degC is 33.8Deg F
Then why isnt double of 1DegC ie 2Deg C double of 33.8Deg F.

This is the conversion:
1 C ...........33.8 F
2 C ...........35.6 F
But surely if double of one is two then double of 33.8 should be 67.6?

Ksp for Pb(OH)2=8*10^-16. In presence of excess hudroxide, the formation of a soluble hydroxo complex of lead(II) may be significant. The equilibrium reaction is
Pb+2(aq) + 3OH- (aq) <=> Pb(OH)3 (superscript -2)

Consider a saturated solution of lead(II) hudroxide at pH 12.0. Calculate the molar concentration of free lead(II) ion, Pb+2
