the litmus paper turns red when in contact with phosphoric acid
Litmus paper dipped in coke will turn red, indicating that the solution is acidic. This change in color occurs because coke is a carbonated beverage containing phosphoric acid and citric acid.
Red color in acidic solutions and blue color in basic solutions.
Soap is typically basic in nature, so when it comes into contact with blue litmus paper, it can turn the paper from blue to red. This color change occurs because the soap's alkaline properties react with the litmus dye, causing it to change color.
Yes, turning litmus paper red from blue is a chemical change because the color change results from a chemical reaction between the litmus paper and the substance it comes into contact with, indicating a change in the chemical composition of the paper.
there natural color it did not change their color
Red litmus solution would turn blue if dipped in phosphoric acid, because phosphoric acid is acidic and will cause the litmus paper to change color from red to blue.
The colors of phosphorus are white, yellow, red, violet and black.
Litmus paper dipped in coke will turn red, indicating that the solution is acidic. This change in color occurs because coke is a carbonated beverage containing phosphoric acid and citric acid.
The color of litmus paper turns red when it comes in contact with an acidic solution, and blue when it comes in contact with a basic solution. The color change of litmus paper can help determine the pH level of the substance being tested.
Dry HCl gas does not change the color of litmus paper because it does not contain any water molecules to dissociate into H+ ions, which are responsible for the acidic properties that change the color of the litmus paper. Dry HCl gas does not produce any H+ ions when it comes in contact with water-free litmus paper, so there is no color change observed.
Red litmus turns blue when it comes into contact with a household cleaner containing ammonia. This color change occurs because ammonia is a base that reacts with the litmus paper, causing it to turn blue.
An acid will change litmus paper to red.
No, ethanoic acid does not change the color of blue litmus paper. Blue litmus paper remains blue when in contact with ethanoic acid, as it is a weak acid and does not provide a strong enough acidic environment to turn the blue litmus paper red.
Red color in acidic solutions and blue color in basic solutions.

Yes, turning litmus paper red from blue is a chemical change because the color change results from a chemical reaction between the litmus paper and the substance it comes into contact with, indicating a change in the chemical composition of the paper.
No, sugar cannot change blue litmus to red. Litmus paper changes color based on the acidity or alkalinity of a solution, not because of the presence of sugar. Sugar does not have any effect on the color change of litmus paper.
