Differentiate among acidic, basic, and neutral solutions (in terms of the relative amounts of hydrogen ions and hydroxide ions).

• Acidic solutions have more hydrogen ions (H+) than hydroxide ions (OH-). Basic solutions have more hydroxide ions (OH-) than hydrogen ions (H+). Neutral solutions have equal amounts of hydrogen ions and hydroxide ions.

• Acidic solutions have more hydroxide ions (OH-) than hydrogen ions (H+). Basic solutions have more hydrogen ions (H+) than hydroxide ions (OH-). Neutral solutions have more hydrogen ions than hydroxide ions.

• Acidic solutions have equal amounts of hydrogen ions and hydroxide ions. Basic solutions have more hydrogen ions than hydroxide ions. Neutral solutions have more hydroxide ions than hydrogen ions.

• Acidic solutions have more hydroxide ions than hydrogen ions. Basic solutions have equal amounts of hydrogen ions and hydroxide ions. Neutral solutions have more hydroxide ions than hydrogen ions.

Identify the color change of different indicators (Phenolphthalein, Methyl orange, Litmus paper) in acidic, basic, and neutral mediums using a mini lab.

• Phenolphthalein: Colorless in acid, pink in base. Methyl orange: Red in acid, yellow in base. Litmus paper: Red in acid, blue in base.

• Phenolphthalein: Pink in acid, colorless in base. Methyl orange: Yellow in acid, red in base. Litmus paper: Blue in acid, red in base.

• Phenolphthalein: Colorless in acid, yellow in base. Methyl orange: Pink in acid, red in base. Litmus paper: Red in acid, yellow in base.

• Phenolphthalein: Red in acid, blue in base. Methyl orange: Colorless in acid, pink in base. Litmus paper: Yellow in acid, pink in base.

Imagine you have three clear, colorless liquids. One is an acid, one is a base, and one is neutral. I'm thirsty and want to drink one, how can I know which is the water?

• By testing each liquid with an indicator to find the neutral one.

• By tasting each liquid to see which is water.

• By smelling each liquid to identify water.

• By checking which liquid is colder.
