What is the Bronsted-Lowry definition of an acid?

• A substance that accepts a proton (H+)

• A substance that has a high pH level

• A substance that donates a proton (H+)

• A substance that donates an electron

What is the Bronsted-Lowry definition of a base?

• A substance that can accept a proton

• A substance that can conduct electricity

• A substance that can donate a proton

• A substance that can change color in a pH indicator test

What is the pH scale and how is it related to the concentration of H+ ions?

• The pH scale measures the pressure of a solution and is related to the concentration of H+ ions.

• The pH scale measures the temperature of a solution and is related to the concentration of H+ ions.

• The pH scale measures the color of a solution and is related to the concentration of H+ ions.

• The pH scale measures the acidity or basicity of a solution and is related to the concentration of H+ ions.

What are indicators and how are they used to determine the pH of a solution?

• They are substances that change color in response to the pH of a solution and are used to visually determine the pH of a solution.

• They are used to measure the volume of a solution

• They are used to measure the temperature of a solution

• They are used to determine the color of a solution

What is a neutralization reaction and give an example?

• A neutralization reaction is a chemical reaction between an acid and a base, resulting in the formation of water and a salt. An example is the reaction between hydrochloric acid and sodium hydroxide to form water and sodium chloride.

• A neutralization reaction is a physical reaction between an acid and a base, resulting in the formation of water and a gas. An example is the reaction between acetic acid and calcium hydroxide to form water and carbon dioxide.

• A neutralization reaction is a chemical reaction between two acids, resulting in the formation of water and a salt. An example is the reaction between sulfuric acid and hydrochloric acid to form water and sodium chloride.

• A neutralization reaction is a chemical reaction between a base and a salt, resulting in the formation of water and an acid. An example is the reaction between sodium hydroxide and potassium chloride to form water and hydrochloric acid.

What are the products of a neutralization reaction between hydrochloric acid and sodium hydroxide?

• Hydrogen gas and sodium hydroxide

• Water and sodium chloride

• Oxygen and hydrochloric acid

• Carbon dioxide and sodium chloride

What is the strength of an acid and how is it related to its ionization in water?

• The strength of an acid is related to its color

• The strength of an acid is related to its ionization in water.

• The strength of an acid is related to its boiling point

• The strength of an acid is related to its sweetness

What is the strength of a base and how is it related to its ionization in water?

• The strength of a base is related to its color

• The strength of a base is related to its ionization in water.

• The strength of a base is related to its boiling point

• The strength of a base is related to its sweetness

What are the common properties of acids?

• Salty taste, turn red litmus paper red, pH less than 7

• Sour taste, turn blue litmus paper red, pH less than 7

• Sweet taste, turn red litmus paper blue, pH greater than 7

• Bitter taste, no effect on litmus paper, pH equal to 7

What are the common properties of bases?

• Sweet taste, slimy texture, turn red litmus paper green

• Bitter taste, slippery feel, turn red litmus paper blue

• Sour taste, rough texture, turn blue litmus paper red

• No taste, dry texture, turn blue litmus paper yellow
