pH and Acidity

• pH is a measure of the concentration of hydrogen ions in solutions, specifically in acidic and alkaline solutions.

Physical Change

• A physical change occurs when a substance changes its form without forming a new substance, meaning its chemical composition remains the same.

Physical Mixtures

• A physical mixture is a combination of two or more substances that are united physically, but not chemically, and can be separated using physical methods.

Physical Properties

• Physical properties are characteristics of matter that can be determined and measured without undergoing a chemical reaction, such as texture, color, and melting point.

Reduction

• Involves the subtraction of oxygen from a substance
• Alternatively, it involves the addition of hydrogen to a substance
