Multiply by 2 because calcium hydroxide = Ca(OH)2 so 2 x [OH-] per molecule.[OH-] = 0.0131 x 2 = 0.0262Insert [OH-] value into the equilibrium equation along with the value of Kw at 10 degrees centi...
An acidic buffer solution is made up of a weak acid (e.g. ethanoic acid) and a salt containing its conjugate base (e.g. sodium ethanoate). It resists pH change via two mechanisms: The fact that the acid i...
The process is fractional distillation: the separation of a mixture using heat. The crude oil is heated and the mixture will evaporate. The mixture will then rise...
A lattice of positive sodium ions with a sea of delocalised electrons distributed around them. The metallic bond consists of the electrostatic force of attracion between the positively charged sodium atom...
