Blue litmus paper would be used and if the chemical is an acid the litmus paper would turn red.
It turns from blue to red or red to blue.ANS2:Acetone will not change the colour of litmus. It is not an ionic substance so it will not produce a change in pH.
If red litmus paper is dipped in potassium sulfate solution, there will be no significant change in color. Potassium sulfate is a neutral salt and does not exhibit any acidic or basic properties that would cause a color change in litmus paper.
Baking soda is a basic compound, so it would turn blue litmus paper red as it causes the paper to change color in the presence of a base.
When a base is added to red litmus paper, the indicator turns blue. This is because red litmus paper is used to indicate acidic conditions, so a base would cause the paper to change color to blue.
It would remain red, red litmus paper only reacts to blue in the presence of a base. Lemon juice is acidic and thus wouldn't turn the paper a color. If blue litmus paper was used in the lemon juice it would turn red. Consequently dipping blue litmus paper in a base won't change the color because it does not react with bases, only acids.
Blue litmus paper would turn red in orange juice.
It is because the red litmus paper only changes its color (from red to blue) when exposed to any basic substance. Hydrochloric acid is acidic, thus there is no change in the color of the red litmus paper, although the acid would change the color of the blue litmus paper (pH paper that tests for acidity; changes from blue to red in the presence of acid)
red
It turns from blue to red or red to blue.ANS2:Acetone will not change the colour of litmus. It is not an ionic substance so it will not produce a change in pH.
Actually, some acids do burn litmus paper. Hydrochloric acid, for example, can burn paper, but the litmus on litmus paper shields the paper from the acid. Sulfuric acid, however, has dehydration properties, and would suck the water right out from the paper, charring it instantly.
the litmus paper turns red when in contact with phosphoric acid
Apple juice is a type of citric acid so it would turn blue litmus paper redish.
Litmus paper would turn red if apricot juice, which is acidic, was dropped on it. This is because litmus paper turns red in the presence of an acid.
If red litmus paper is dipped in potassium sulfate solution, there will be no significant change in color. Potassium sulfate is a neutral salt and does not exhibit any acidic or basic properties that would cause a color change in litmus paper.
Baking soda is a basic compound, so it would turn blue litmus paper red as it causes the paper to change color in the presence of a base.
Sodium hydroxide is a strong base, so it will turn blue litmus paper to red. This color change is due to the alkaline nature of sodium hydroxide which reacts with the blue litmus paper to change its color.
When a base is added to red litmus paper, the indicator turns blue. This is because red litmus paper is used to indicate acidic conditions, so a base would cause the paper to change color to blue.
