Because if you only use red litmus paper and the solution you tested kept the paper red, you would think that the solution would also make the blue litmus paper turn red too. But what if the solution was neutral? Then the blue litmus paper would stayblue instead of turn red. Thats why you need to use both blue and red litmus paper.
As soap is alkaline in nature, it turns red litmus paper blue
Red litmus paper turns blue in basic solutions, while blue litmus paper turns red in acidic solutions. By using both types of litmus paper, you can determine if a solution is acidic if blue litmus turns red or basic if red litmus turns blue. This allows for a more accurate determination of the pH of a solution.
the red litmus paper turns to blue
Milk of magnesia is basic, so it will turn red litmus paper blue and have no effect on blue litmus paper.
Red litmus paper is used to test for acids. If the red litmus paper turns blue when dipped in a substance, it indicates the presence of an acid.
An acid turns the blue litmus paper red.
An acidic solution will change blue litmus paper to red and basic solutions change red litmus paper to blue
Litmus paper is used to determine if a chemical is acid or alkali. Litmus paper turns red in acidic solutions and blue in alkaline solutions.
yes a blue litmus paper turns red when put into an acid
Yes, the litmus paper test can determine if an aqueous solution is basic. If the litmus paper turns blue, it indicates that the solution is basic. If it remains red, the solution is acidic.
When litmus paper touches an acid, the paper changes to red. When it touches a base, the paper changes to blue. By comparing the color the litmus paper changed to by a chart, you could determine how strong or weak that acid or base is.
it is litmus not lithmus . it is a natural indicator . it is a strip of paper either red or blue in colour . it is used whether a solution is acidic or basic in nature. a basic solution turns red litmus to blue and an acidic solution turns blue litmus into red
As soap is alkaline in nature, it turns red litmus paper blue
Blue litmus paper turns red in acid red litmus paper turns blue in alkali.
