Solutions with excess H+ ions; the more H+ ions, the more acidic.

Solutions with excess OH- ions; Can accept hydrogen ions.

Acids can break down certain substances like fabric or skin.

Bases often feel slippery when touched.

Acids taste sour.

Bases like soaps and ammonia contain OH⁻ ions that interact strongly with dirt and grease, making them easier to remove.

A scale that measures how acidic or basic a solution is. Values below 7 are acidic, 7 is neutral, and above 7 are basic.

Indicates a solution is acidic, meaning it has a higher concentration of H+ ions.

Indicates a solution is basic (or alkaline), meaning it has a higher concentration of OH⁻ ions.

Human blood is slightly basic, with a pH typically around 7.35 to 7.45. This is crucial for optimal bodily function.

A molecule composed of two hydrogen atoms and one oxygen atom (H₂O). The atoms are held together by covalent bonds.

A molecule with an uneven distribution of electrical charge, resulting in a positive and a negative end.

Water molecules sticking to each other due to their polar nature and hydrogen bonding.

Water molecules sticking to other substances, like the walls of a narrow tube, due to their polar nature.

Water can dissolve more substances than any other liquid due to its polarity and ability to form hydrogen bonds.

Water exists naturally as a solid (ice), liquid (water), and gas (vapor).

The amount of heat energy required to convert liquid water into water vapor (gas).

Water's hydrogen bonds are very strong, so breaking them requires a significant amount of energy.

Water freezes at 0°C or 32°F, making it unique as the only liquid that freezes completely solid.

Unlike most liquids, water expands when it freezes, causing ice to float.
