Overview

Acids, bases and salts form an important part of everyday chemistry. Acids taste sour and furnish hydrogen ions in water, bases taste bitter and furnish hydroxide ions in water, and salts are ionic compounds formed in many reactions between acids and bases. The chapter connects observable properties

Key Concepts

An acid furnishes hydrogen ions

An acid furnishes hydrogen ions in water, while a base furnishes hydroxide ions in water. Acids are sour, bases are bitter and soapy to touch. Robert

Indicators change colour in acidic

Indicators change colour in acidic and basic media. Litmus is red in acid, blue in base, and purple in neutral solution. Phenolphthalein is colourless

Strong acids and bases dissociate completely

Strong acids and bases dissociate completely in water, while weak acids and bases dissociate only partially. HCl, HBr, HI, HClO4, HClO3, H2SO4, and HN

Acids and bases show their acidic

Acids and bases show their acidic or basic nature only in aqueous solution. Dry HCl gas does not turn dry blue litmus red, and dry solid NaOH does not

Neutralization is the reaction of

Neutralization is the reaction of an acid with a base to form salt and water. It reduces acidic and basic properties. Acid-metal, acid-carbonate, acid
