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.
