What is neutralization in chemistry?

Back

Neutralization is a chemical reaction between an acid and a base that produces salt and water.

Front

What is the pH scale?

Back

The pH scale measures how acidic or basic a solution is, ranging from 0 (most acidic) to 14 (most basic), with 7 being neutral.

Front

What pH value indicates a strong acid?

Back

A pH value less than 7 indicates an acidic solution, with lower values being more acidic.

Front

What is a heating curve?

Back

A heating curve is a graph that shows the change in temperature of a substance as it is heated over time, illustrating phase changes.

Front

Between what temperatures are substances in the liquid state according to a heating curve?

Back

Substances are in the liquid state between their melting point and boiling point.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where two compounds exchange ions to form two new compounds.

Front

What do subscripts in a chemical formula indicate?

Back

Subscripts indicate the number of atoms of each element in a molecule.

Front

What is the difference between an acid and a base?

Back

Acids donate protons (H+) in a solution, while bases accept protons.

Front

What is the formula for calculating pH?

Back

pH = -log[H+], where [H+] is the concentration of hydrogen ions in moles per liter.

Front

What is the role of water in neutralization reactions?

Back

Water is produced as a byproduct in neutralization reactions between acids and bases.
