What are all the types of acid? What is the strongest and how is it made?
Question Date: 2007-11-04
Answer 1:

We measure how strong an acid is by using the pH scale. On the pH scale, 7 means neutral. A number bigger than 7 means that something is alkaline (also called basic), and numbers smaller than 7 mean that something is acidic. It is an unusual scale because each step is 10times as big as the step before. For example, something with a pH of 5is 10 times as acidic as something with a pH of 6. Something with a pHof 4 is 100 times as acidic as something with a pH of 6.

Please look at the following web sites. They are about the pH scale, how it works and how to read it:

Things that are either very acidic or very basic are also dangerous.They can corrode your skin, basically eating it away. Mixing acids and bases can cause explosions.

The strongest "common" acid is concentrated sulfuric acid, but there are apparently "super acids" that are even stronger.

I'm not a chemist, so I don't know how a person would make sulfuric acid, but I can tell you that sulfuric acid is extremely dangerous. If you are interested in becoming a chemist, this is the sort of thing you would study. You would also learn how to safely handle chemicals.

You can explore acids and bases by using weak ones, like vinegar (which is acidic), and baking soda (which is basic or alkaline). Just get help from an adult and be prepared to clean up.

Thanks for asking,
