Answer 2

On putting a drop of liquid on a pH paper a student observed a small patch of blue colour on pH paper. The liquid is most probably a) Water and c) Sodium-hydroxide

Step-by-step explanation:

a) Water

• The pH of water, In its purest form water has a pH of 7, which is at the exact center of the pH scale.

• Particles in the water can change the pH of the water, and most water for use has a pH of somewhere between 6.5 and 8.5 and blue colour on pH paper.

c) Sodium-hydroxide

• Using a pH indicator strip will tell you that NaOH (sodium hydroxide) is a strong alkaline. This means it has a pH toward the top end of the pH scale, which ranges from 0 to 14.

• Soaps, rayon, paper, explosives, colours, and petroleum products are all made with sodium hydroxide. It can also be used for cotton fabric processing, metal cleaning and processing, oxide coating, electroplating, and electrolytic extraction, among other things.

• It's commonly found in store-bought drain and oven cleansers.
