The reaction between acid and base is called combustionNeutralizationsynthyesisSave

The reaction between an acid and a base is specifically called neutralization. In this type of reaction, an acid reacts with a base to produce a salt and water. The general form of the reaction can be represented as:

$\text{Acid} + \text{Base} \rightarrow \text{Salt} + \text{Water}$

Neutralization is an important chemical reaction with practical applications in various fields, including biology, medicine, and environmental science. This reaction helps in balancing pH levels in different solutions. For example, when treating acidic soil, a base (like lime) can be added to neutralize the pH, promoting better plant growth.

The other terms in your question, such as "combustion" and "synthesis," refer to different types of chemical reactions. Combustion involves the burning of a substance in the presence of oxygen, typically producing heat, light, and various gases. Synthesis, on the other hand, is a reaction where two or more reactants combine to form a single product. Therefore, when discussing the reaction between acids and bases, the correct term is neutralization.
