Today In Science we are looking at an experiment to do with Nuetralisation.
FACTS:
Universal Indicator - Shows if its an acid or a base. - By changing colour
Blue Green Red = pH Scale.
Acid is red, base is blue but if it turns green it is neutral which means its both.
The pH scale goes from one to fourteen.
This nuetralisation experiment is using a base and an acid but trying to turn them green to become neutral
An acid is:
Sour
Sweet
Corrode
A Base is:
Its the opposite of the acid and it has a difference with an alkali
Bases that dissolves in water are called alkali's
These picture shows our experiment we did today using Sodium hydroxide, Hydrochloric acid and universal indicator. This is my pH scale that i created using those 3 ingredients
Well done Kyra, next time could you please explain why/how you managed to get the different colours? what was happening in the beakers?
ReplyDeleteYou did a great job at making/showing the different strengths :)
