Multiply by 2 because calcium hydroxide = Ca(OH)2 so 2 x [OH-] per molecule.[OH-] = 0.0131 x 2 = 0.0262
Insert [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 molecule with the highest boiling point is ethanol. This is because of the hydrogen bonding that occurs between molecules from the electronegative oxygen atom and electropositive hydrogen atom. The s...

Haemoglobin is a complex metal ion consisting of hexa-coordinated Fe²⁺ ions. With 6 coordinate bonds, haemoglobin forms an octahedral shape where 4 nitrogen ligands form a haem disc, a globin m...

SN1= only 1 species involved in the rate determining step = carbocation intermediate = racemic mixture = not optically active SN2= 2 species involved in the rate determining step =transition state = singl...
