Acid rain lowers the pH of river water when it flows into rivers, making it difficult for aquatic life to survive.

Rainwater with a pH below 5.6 is termed as acid rain, which can have detrimental effects on ecosystems, including harming aquatic life and damaging vegetation and infrastructure.

The human body operates within the pH range of 7.0 to 7.8, maintaining a slightly alkaline environment crucial for various physiological processes and overall health.

The strength of acids and bases depends on the number of H+ ions and OH– ions they produce, respectively. Strong acids produce more H+ ions, while weak acids produce fewer H+ ions.

Paper impregnated with universal indicator is commonly used for measuring pH. The indicator changes color depending on the acidity or alkalinity of the solution, allowing for pH determination.

As the pH value increases from 7 to 14, it represents an increase in the concentration of OH– ions in the solution, indicating an increase in the strength of the alkali.

Acidic solutions are represented on the pH scale by having pH values less than 7. The lower the pH value, the more acidic the solution is considered to be.

The pH of a neutral solution is 7, which is represented as neither acidic nor alkaline. It marks the midpoint on the pH scale.

The pH scale measures the acidity or basicity of a solution. It ranges from 0 (very acidic) to 14 (very alkaline), with lower pH values indicating higher hydronium ion (H3O+) concentrations and higher acidity, and higher pH values indicating higher ...

A universal indicator is a mixture of several indicators that change color at different concentrations of hydrogen ions in a solution. It provides a range of colors to indicate the pH of a solution.
