What will be change when red litmus paper is dipped into bicarbonate of soda,distilled water, rain water,white win.
To determine the effect on the color of blue litmus paper when dropped in each of the solutions mentioned, you need to understand the color-changing properties of litmus paper. Blue litmus paper is typically used as an indicator to detect the presence of an acidic substance.
Here's how you can predict the outcomes:
1. Water: When blue litmus paper is dropped into water, it will remain blue. Water is considered neutral and does not affect litmus paper, so there is no color change.
2. Lime Juice: Lime juice is acidic, and when blue litmus paper is placed in an acidic solution, it will turn red. So, if you drop blue litmus paper into lime juice, it will turn red.
3. Dilute Hydrochloric Acid: Hydrochloric acid is highly acidic. Therefore, when blue litmus paper is exposed to dilute hydrochloric acid, it will also turn red.
4. Sodium Hydroxide Solution: Sodium hydroxide solution is highly alkaline or basic. In basic solutions, blue litmus paper will remain blue as it is not affected by alkaline substances.
In summary, the color of blue litmus paper will not change in water or sodium hydroxide solution, but it will turn red in the presence of lime juice or dilute hydrochloric acid.
