HELP ASAP I WILL GIVE BRAINLIST

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

Answer 1

Explanation:

• The pH scale measures how acidic an object is. Objects that are not very acidic are called basic. The scale has values ranging from zero (the most acidic) to 14 (the most basic)
• Strong acid is an acid that ionizes completely in aqueous solution. It always loses a proton (H+) when dissolved in water. Weak acid is an acid that ionizes partially in a solution. It gives off only a few of its (H+) atoms when dissolved in water.

Answer 2

Answer:

The pH scale is used to measure the acidity or basicity of a substance.

Explanation:

pH stands for potential hydrogen. It ranges from 0 to 14, 7 being neutral. The pH of water is 7 i.e. it is neither acidic nor basic. 0 to 7 shows acidic behavior while 7 to 14 shows basic behavior.

Experiment:

• Dip the pH paper in the liquid and wait for ten seconds. The pH strip starts to discolor.
• For a strong acid the strip will turn red.
• For a weak acid the strip will become pale red.
• To find the correct pH value we can compare it with the indicator scale present on the pH scale box.
