Akosua has observed that anytime she drinks sobolo, her stool appears dark green. On one occasion Akosua observed that her stool, which appeared dark green, turned quickly to bright red upon mixing with the perchloric acid-treated WC water.

i. What about the sobolo drink (bright red) that made the stool of Akosua green?

ii. Why did the stool of Akosua, which appeared green because she took sobolo drink, turn into

bright red upon mixing with the acidic WC water?

iii. Suggest a practical use of sobolo drink in the identification of chemicals in the science laboratory .

perchloric acid treated WC water

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
