What will be the observation when a piece of blue litmus paper is dropped in a distilled water and a rain water.
What observation will be made if piece of blue litmus paper is dropped in each of the following 1 sodium hydroxide
2 dilute hydrochloric acid
3 lime juice
4 distilled water
5 rain water
depends on the pH of the rain water.
What does blue litmus paper test for?
I want answers to some questions
What observation will be made if a piece of blue litmus paper is dropped in each of the following 1.Rain water 2.Lime juice 3.Distilled water
I don't know so teach me
It depends on its pH and what it is reacting with. usually remains the same
To determine the observation when a blue litmus paper is dropped in distilled water and rainwater, you will need to understand the basic concept of litmus paper and how it reacts to different substances.
Litmus paper is a pH indicator commonly used in laboratories. It consists of a filter paper treated with a mixture of natural dyes extracted from lichens. Blue litmus paper turns red in an acidic solution and remains blue in a neutral or basic solution.
Now, let's consider the two scenarios:
1. Distilled Water: Distilled water is pure water with a neutral pH value of 7. When a blue litmus paper is dropped into distilled water, it will remain blue, indicating that distilled water is neither acidic nor basic.
2. Rainwater: Rainwater, on the other hand, can vary in pH depending on various factors such as atmospheric pollution, the presence of dissolved gases, and the environment it is collected from. However, generally, rainwater is slightly acidic due to the presence of dissolved carbon dioxide, which forms carbonic acid. When a blue litmus paper is dropped into slightly acidic rainwater, it will turn red, indicating the presence of acidity.
To summarize, the observation will be that the blue litmus paper remains blue in distilled water, indicating neutrality, and turns red in rainwater, indicating slight acidity.
