Firstly calcuate the moles of KMnO4 by using the equation n=MV/1000 where n=moles M=molarity (moldm^-3) and V= volume (cm³). As the question gives the molarity and volume of KMnO4 you...

Firstly, I would try and establish with the tutee what a buffer is and define it. Going through the key aspects of what a buffer is. The standard definition I have for a buffer is 'A solution that minimis...

Approach this question in a logical manner breaking it down into constituent parts and then explaining these in turn.

1. Give a defination for acidity i.e. pH: pH=-log10[H+] or pKa=-long10Ka...

In these multiple part questions, it is often the case that the previous part of the question will provide necessary information for answering the following parts, as hinted by the use of 'hence'. It's ve...

We need to think about the number of atoms of each element in the reactants and ensure these are the same in the products.

This is the basic UNBALANCED equation.
