Acids are corrosive
Bases are corrosive
A litmus test can determine the pH level of a substance
The following are examples of bases: vinegar, lemon juice, tea
The pH level of pure water is 7
Toothpaste is not an acid
The pH level of lime water is 16
When tested with Universal Indicator, the most acidic substances will turn this colour
violet
orange
red
green
A substance with pH7 will come up this colour when tested with Universal Indicator
blue
An alkali is a(n) acid base( acid, base ) that is dissolved in water
When the properties of an acid are counteracted by a base, the reaction is called titration neutralisation( titration, neutralisation )
Titration is a method used to:
make a basic substance as acidic as possible
find out the exact amount of acid required to just neutralise a certain volume of a base
keep litmus paper from going mouldy in the lab
burn a strip of magnesium oxide
Neutralisation reaction: ACID + BASE → Salt Copper Toothpaste( Salt, Copper, Toothpaste ) + lime pipette water( lime, pipette, water )
