Several theories have been developed to explain the behaviour of acids and bases. The most notable theories include the Arrhenius concept, the Brønsted-Lowry theory, and the Lewis concept. In the ...

Many chemicals can be classified as being acidic, neutral or alkaline by using indicators. The pH scale is used to measure acidity and alkalinity. When an acid is neutralised, it forms a salt. Making ...

Welcome to science world. Now everyone loves a wee bag of chips, don’t they? Maybe a wee pasty or a battered sausage and if you’ve any sense you’ll cover it in a bit of vinegar. But did you know that ...

In chemistry, the classification of substances into acids and bases is fundamental. Within this spectrum, strong bases, such as sodium hydroxide and calcium hydroxide, are potent agents capable of ...

Salt is an ionic compound that results from the neutralization reaction of an acid and a base.It is composed of related numbers of cations (positively charged ions) and anions (negative ions) so that ...

The pH of acidic, basic, and neutral aqueous solutions of salts is shown with ammonium chloride, sodium acetate, and sodium chloride. Place beakers containing distilled water and universal indicator ...

An acid-base indicator is a substance that changes color as the pH of the solution changes. Indicators work because they are weak acids which when in solution, exist in equilibrium with their ...

A well-established technique, acid-base titration is an analytical method used to determine the concentration of an unknown acid or base. In practice, it involves adding a solution of known strength ...
