Acids And Bases Flashcards
Bases
Indigestion, soap, toothpaste, bread soda, window cleaner, shampoo
Acids in the lab
Hydrochloric acid, also found in the stomach. Sulphuric acid, also found in car batteries.
Bases in the lab
Sodium hydroxide - naOH
limewater - Ca(OH)2
Acid
Lemons, vinegar, vitamin C, grapes, rhubarb, fizzy drinks, tea, apples
pH
We can tell how acidic or basic a substance is by measuring something called pH
Alkali
A base that dissolves in water
Neutral
If something is neither an acid or 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 eachother. A salt and water are produced.
Indigestion
Excess stomach acid, take an antacid (anti-acid) which is a base
Bee sting
A bee sting is acidic, rubbing a base e.g bread soda will neutralise it
Wasp sting
A wasp sting is alkaline this needs to be treated with an acid e.g vinegar
Titration
An experiment to neutralise an acid (hydrochloric acid) with a base (sodium hydroxide) is called titration
The products of the titration
Salt and water
Indicator paper
An indicator changes colour to tell us if something is an acid or a base
Acid turns Blue litmus paper
To red
