• That Jupiter’s gravitational force is much stronger than Earth’s gravitational force.

• That Jupiter’s and Earth’s gravitational forces are equal.

• Mass has no effect on the gravitational force between two objects

A student makes a pH indicator from red cabbage that has a reddish-purple color with a pH of approximately 7. The student pours the same amount of the cabbage solution into each of four different beakers. He then adds a different household solution to each of the four beakers until a color change is obtained. His results are shown in the table below. Based on the information in the passage, which household solution has the lowest pH? (SC.8.P.8.8)

• club soda

• drain cleaner

• lemon juice

• window cleaner

If the pH of a solution is 9, it is a....

• acid

• base

• both

• none

What might happen if you mixed a strong acid with an equally strong base?

• You would see an explosive chemical reaction.

• The acid would destroy the base.

• The base would destroy the acid.

• You'd wind up with a pH-neutral substance.
