Litmus paper usually turns either blue or pink (sometimes red) which indicates whether the chemical is an acid or a base. If the paper turns blue it is a base. If pink or red it is an acid.
red
HCl (hydrochloric acid) is an acid so it will turn litmus paper red. and alkali will go from red litmus to blue.
As soap is alkaline in nature, it turns red litmus paper blue
Red litmus paper does not change color when it rains; it remains red. Litmus paper is used to test pH levels, and rainwater is typically neutral to slightly acidic, which does not affect the color of red litmus paper. The color change occurs when red litmus paper is exposed to a basic (alkaline) solution, turning blue.
The ink on the litmus paper is lifted up through capillary action, where the ethanol solvent moves up the paper due to its attraction to the paper fibers. This allows the solvent to carry the ink components along with it, separating them based on their chemical properties.
red
Blue litmus paper turns red under acidic conditions and red litmus paper turns blue under acidic conditions.
Red, and an alikili goes blue.
Blue litmus turns red in the presence of an acid. The opposite is correct in case of a base ie in presence of a base, red litmus turns blue in colour.
HCl (hydrochloric acid) is an acid so it will turn litmus paper red. and alkali will go from red litmus to blue.
If the vinegar is strong enough to be below 4.5 pH the litmus paper will turn (or stay) red.
Color of litmus will change.Red litmus will change into blue.
The litmus paper will turn red in the presence of magnesium oxide formed when magnesium is burnt in air. Magnesium reacts with oxygen to form magnesium oxide, which is a basic substance that turns red litmus paper blue.
Hydrochloric acid is an acidic solution, so when litmus powder is added to it, the litmus powder would most likely turn red. This is because litmus paper turns red in acidic solutions and blue in basic solutions.
Litmus turns red when exposed to an acidic solution. Litmus is red in acid and blue in alkali.
HCl (hydrochloric acid) is an acid so it will turn litmus paper red. and alkali will go from red litmus to blue.
Ammonia is a base, and will turn red litmus blue.
