Question

NEED HELP ASAP!!!!!! Trinity conducted a science experiment using household products. She put a drop of a substance on a piece of litmus paper and it turned blue. What is the most probable substance that Trinity tested?

A. water

B. orange juice

C. baking soda

D. vinegar

Answer 1

C. baking soda

Step-by-step explanation:

Litmus papers paper are usually use to test is a solution is acidic or alkaline in nature.

When a blue litmus paper is dipped into an acidic solution, it turns the blue litmus paper red. For example a vinegar solution turns the blue litmus paper red

When a red litmus paper is dipped into an alkaline solution, it turns the paper blue. For example; a solution of baking soda turns a red litmus paper blue

Water do not change the color of either the red litmus paper or blue litmus paper.

So in the question above, since the drop of substance she put on a piece of litmus paper turns the paper blue, this means the substance is a baking soda, from our explanation above, baking soda turns red litmus paper blue.

Answer 2

C

Step-by-step explanation:

Litmus paper detects pH. The pH of the items are as follows:

Water - neutral

Orange juice - acidic

Baking soda - alkaline

Vinegar - acidic.

Litmus paper is red when it is in contact with an acidic substance, green when in contact with a neutral substance, and blue when it is contact with an alkaline substance. Therefore, Trinity likely tested baking soda, an alkaline substance (C)
