Overview
Acids, bases and salts are linked through their chemical reactions, their behaviour in water, and their many uses in daily life. Acids produce hydronium ions in water and show acidic properties, bases produce hydroxide ions and show basic properties, and neutralization between an acid and a base for
Key Concepts
Acids are substances that produce H3O+
Acids are substances that produce H3O+ ions in water, while bases produce OH- ions in water. Acids turn blue litmus red, and bases turn red litmus blu
Litmus is a natural indicator from
Litmus is a natural indicator from lichen. Phenolphthalein and methyl orange are synthetic indicators. Universal indicator is a mixture of indicators
Acids generally react with metals
Acids generally react with metals to form salt and hydrogen gas. Zinc with dilute HCl gives zinc chloride and hydrogen gas.
Bases can also react with some
Bases can also react with some metals. Zinc reacts with NaOH to form sodium zincate and hydrogen gas.
Metal carbonates and metal hydrogen carbonates
Metal carbonates and metal hydrogen carbonates react with acids to form salt, carbon dioxide, and water. Carbon dioxide turns limewater milky due to c
