Question

What are examples of strong acids and bases, weak acids and bases, and neutral substances according to the pH scale?

Answer 1

The six strong acids that you should remember are
`HCl`
`HBr`
`HI`
`H_2SO_4`
`HNO_3`
`HClO_4`
Any other acid that you see you can consider a weak acid.

For strong bases, any hydroxide (`OH^-`) is considered strong. The base has better solubility if it is in a 1:1 ratio with the metal that it is bonded to.

For example, `Ca(OH)_2` is not as soluble as `NaOH` .
