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)

Household Solution - Color of Mixture

Lemon juice - Bright pink

Club soda - Light pink

Window cleaner - Light blue

Drain cleaner - Greenish-yellow

• club soda

• drain cleaner

• lemon juice

• window cleaner

• The particles of a liquid slide past each other.

• The particles of a liquid vibrate and barely move.

• The particles of a liquid do not move at all.

A golf ball and a ping-pong ball are about the same size. In other words, they have about the same volume. However, a golf ball has more mass than a ping-pong ball. What can you conclude from this information?

• A ping-pong ball contains more matter than a golf ball.

• A ping-pong ball has the same properties as a golf ball.

• A golf ball contains a smaller amount of mass per volume than a ping-pong ball.

• A golf ball has a greater density than a ping-pong ball.
