National 5 – Volumetric Titration Calculations (try saying that 3 times fast)

Calculations are a key part of National 5 Chemistry (and chemistry in general). Love ’em or hate ’em, you still gotta do ’em.

 

An important part of carrying out calculations is actually understanding what the question is asking and how to tackle it.

Below is a detailed walkthrough of a Volumetric Titration Calculation, where you’re asked to calculate the concentration of a solution but you’re only given a volume. Remember, to calculate number of moles, concentration or volume of a solution you use the following triangle:

However, you need 2 values to be able to calculate the unknown. What the video explains is how you can work out the number of moles of a known solution and use that value (depending on the mole ratio) in your c=n/v calculation.

You can do it!
