What is an acid?

Back

An acid is a substance that donates protons (H+) in a solution, typically having a sour taste and a pH less than 7.

Front

What is a base?

Back

A base is a substance that accepts protons (H+) or donates hydroxide ions (OH-) in a solution, usually having a bitter taste and a pH greater than 7.

Front

What is the pH scale?

Back

The pH scale is a logarithmic scale used to measure the acidity or basicity of a solution, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

What is neutralization?

Back

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

Front

What is the formula for hydrochloric acid?

Back

HCl

Front

What is the formula for sulfuric acid?

Back

H2SO4

Front

What is the formula for nitric acid?

Back

HNO3

Front

What is the relationship between pH and pOH?

Back

pH + pOH = 14; this relationship shows how acidity and basicity are inversely related.

Front

What is the pH of a neutral solution at 25°C?

Back

7

Front

What is the significance of a pH of 7?

Back

A pH of 7 indicates a neutral solution, meaning it is neither acidic nor basic.
