investigate whether substances are basic?

OB. Test each substance with red litmus paper.
O C. Observe each substance and record its color.
OD Test each substance with blue litmus paper.

Respuesta :

Answer:

I think B

Explanation:

Red litmus paper is used more to find bases, blue litmus paper changes better when coming to find acids. So I believe it is B

The best approach best investigate whether substances are basic is to test each substance with red litmus paper.

What is basic compound?

Basic compounds are those which have a pH value in between the range of 7.1 to 14.

Red litmus paper changes its color from red to blue when comes in the contact of basic compounds. So to check the basicity of household substance we should use red litmus paper.

  • Bases are reacting with only acids means bases shows no reaction with base and if we use weak base then we will not get the desired result as weak bases are partially dissociates only.
  • Color will not gives idea about basicity and acidity.
  • Red litmus paper is used to test the acidity of substance as it turns blue when comes in contact of acids.

Hence test each substance with red litmus paper.
