pH
We can tel, how acid or basic something is by measuring something called pH
Alkali
A base that dissolves in water I called an alkali eg drain cleaner (sodium hydroxide)
Neutral
If something is neither an acid nor a base and has a pH of 7 then it is neutral
Neutralisation
If an acid and base are mixed together in the right concentrations, then they neutralise each other
A salt and water are produced
Titration
An experiment to neutralise an acid with a base
The products of titration are….
Salt and water
Indicator paper
Changes colour to tell us if something is an Acid or Base
Acid turns blue litmus paper
Red
Bases turn red litmus paper
Blue
Universal indicator paper
This changes different colours for different pH values, it is compared to the key on the pack
Datalogging
This is where you use a sensor connected to a computer to measure pH
Test for hydrogen
