Describe the scale used to measure the basicity of a substance. Demonstrate how you could differentiate a weak base from a strong one.

The scale used to measure how basic or acidic a substance is, is called the ph scale. It shows how basic or acidic a substance is. How to tell is by having ph paper and sticking the paper in the substance. whatever color the paper turns to coordinates with weather the substance is acidic or basic.

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.
