Answer 2

Most acids are sour.

Most acids corrode metals.

Step-by-step explanation:

Acids:-

Acids are the species which furnish hydrogen ions in the solution or the species which has electron deficient central atom.

Most acids are sour in taste.

Most acids react with the metals and corrode them by making their salt solutions and hydrogen gas.

Acids may contain hydrogen or not. Hydrogen contains acids are
`HCl`,
`H_2SO_4`,
`HNO_3`,
`H_3PO_4`, etc.

Hydrogen non-containing acids are Lewis acids like
`BF_3`,
`AlCl_3`, etc.

They have pH less than 7.

Hence, correct statements are:-

Most acids are sour.

Most acids corrode metals.
