Acids and Bases by

Acids

They are found in Laboratories and even in your house!

The Acids in Laboratories are usually more dangerous since they use it to make experiments

In the Laboratory at school there is usually Dilute acids such as:

-hydrochloric acid

-sulphuric acid

-nitric acid

They usually would have a warning symbol on their bottles, that symbol shows that it is dangerous

If that acid makes contact with your skin, your skin will become red or blistered. If it does spill, you must wash it with a lot of water, otherwise you'll feel as if it is burning

There are also concentrated acids and they are way more dangerous than the dilute acids. This is because they are corrosive, meaning that is it spilled on metal it would just make a hole in the metal. They could also destroy skin if spilled

Bases

Bases are substances that react with acids and neutralize them. They are usually metal oxides, metal hyroxides, metal carbonates or metal hydrogen carbonates. Many bases do not dissolve in water.

If a base does dissolve in water, that is called an alkali

examples of bases:

-Copper oxide is a base because it will react with acids, but it is not an alkali because it does not dissolve in water.

-Sodium hydroxide is a base because it will react with acids and it is also an alkali because it dissolves in water.

All alkalis are bases, but not all bases are alkalis

Then there are also acids in your house, such as:

-Ethanoic acid (in vinegar)

-Carbonic acid (in fizzy drinks)

-Tannic acid (in tea)

-Ascorbic acid (in vitamin C)

-Citric acid (in Lemons)

Acids have a sour taste, like vinegar, which contains ethanoic acids, and lemons which contain citric acid. These are safe to use in food, but still hurts if it gets into our eyes or in cuts.

There are bases in the laboratory that are strong, such as sodium hydroxide solution. These are usually labelled with the warning symbol for 'irritant'.

Alkalis feel soapy when they get on your skin.

Concentrated alkalis are corrosive. They are just as dangerous as concentrated acids, but many people do not realise this.

Bases at home react with oils and fat, so they are pften used in strong household cleaners. Drain cleaners and oven cleaners usually contain sodium hydroxide.

You should wear gloves when using these substances, otherwise they will burn your skin.

Weak bases and alkalis are found in toothpaste, antacid tablets and baking powder.
