A salt is also formed in this reaction. Bases are metal oxides, metal hydroxides and metal carbonates. In the neutralisation reaction between an acid and a metal carbonate, there are three ...

Making salts Acids react with metals, bases and carbonates to produce salts. Neutralisation is the reaction between an acid and a base. Titration and calculations Titration is a method used to ...

A pH or acid-base indicator is a compound that ... change can also be used as evidence that a chemical reaction has occurred. Students will explore what happens during neutralization by using a base ...

This pigment is a natural acid-base indicator. It is blue in neutral substances, like plain water. When an acid like lemon juice gets in the water, a reaction makes the indicator molecule change shape ...

Nucleic acids are complex biological molecules that store and transmit ... In DNA, two complementary strands of nucleotides pair up through hydrogen bonds between the bases (A with T and G with C) to ...
