Acids vs Alkalis taste pH Litmus paper Universal Indicator
Acids // Alkalis Sour // Bitter (soapy feel) pH< 7 // pH>7 turns blue to red // turns red to blue Red to yellow // Blue to Purple
Acids + Metals
(except Gold Silver and Copper) salt + hydrogen Effervescence is observed Colourless, odourless gas is produced Gas produced extinguishes lighted splint with a pop
Acids + Metal Carbonate (CO3 ²–)
salt + carbon dioxide + water Effervesence observed Colourless, odourless gas produced Gas produced forms a white precipitate in limewater
