Multiple Choice

Which statement about acids is FALSE?

• Acids have a pH less than 7

• Acids donate H+ ions in water

• acids can be corrosive

• Acids taste bitter and feel slippery

Multiple Choice

Which statement about bases is FALSE?

• Bases have a pH less than 7

• Bases form OH- ions in water

• Soap, bleach, and detergent are some examples

• Bases can be corrosive

Categorize

Options (12)

pH of 3

tastes sour taste

donates H+ ions in water to make H3O+

tastes bitter

feels slippery

forms OH- ions in water

can be strong

can be corrosive

has a pH less than 7

has a pH greater than 7

neutralizes acids

can cause burns

Sort the following properties into acids, bases, or both

Acids

Bases

Both

Both acids and bases can be strong

A "strong" acid or base means that the 100% of the ions have dissociated (or separated) in the solution. The more ions there are the better a solution can conduct electricity.

A "weak" acid or base means that less than 100% of the ions have dissociated and some have stayed together. These are poor conductors of electricity.

Labelling

Label the columns as either strong or weak

Drag labels to their correct position on the image

strong

weak

Multiple Choice

Which solution will conduct electricity better?

• A strong acid or base because there are more ions available to conduct the electricity

• A weak acid or base because there are fewer ions available to conduct electricity
