Chemistry, Module 5: How much? 

Titration reactions are used to measure acidity 

Ph Numbers

  • An acid has a pH from 0-6
    An acid has a lower pH number, and by adding an acid to a solution, it will decrease the pH. 
  • pH 7 is neutral 

  • An alkali has a pH from 8-14
    An alkali has a higher pH, and by adding an alkali to a solution, the pH will increase.

Measuring pH

The pH of something is measured by a pH meter.

...However, the magic stuff that we play around with in Chemistry lessons, which changes the colour of a liquid is called  Universal Indicator. What could that mean? An indicator - something that indicates, therefore the Universal Indicator will tell us whether the liquid is an Acid, an Alkali or in my favourite case... Neutral

What happens when you add an acid... and an alkali??

Acid + Alkali = Salt + Water

End point: The end point of a titration reaction is the point where the pH, or the pretty colour, changes very suddenly. 

Here comes the hard/detailed part...

So... as we stated earlier, titration reactions are used to measure acidity. In fact, its when there is a new problem up in the smart people lab, that a titration…




Thanks a lot, this is really helpful work!! xoxo



The added humour really made this tolerable to read through, aposed from sitting at a desk listening to the teacher. Well done!
