Question

What is a characteristic property of acids?

Answer 1

Sour taste, react with "active" metals. Change the color of vegetable dyes (`color(blue)(blue)` litmus turns `color(red)(red)`) and react with bases to form ionic salts.

Explanation:

-Sour taste.
-React with “active” metals.
I.e., Al, Zn, Fe, but not Cu, Ag or Au.
`diamond2 Al + 6 HCl-> 2 AlCl_3 + 3 H_2`
`diamond`Corrosive.
-React with carbonates, producing CO2.
`diamond`Marble, baking soda, chalk, limestone.
`diamondCaCO_3 + 2 HCl->CaCl_2 + CO_2 + H_2O`
-Change color of vegetable dyes.
`diamond`Blue litmus turns red.
-React with bases to form ionic salts.
