HCl (hydrochloric acid) is an acid so it will turn litmus paper red. and alkali will go from red litmus to blue.
Lemon juice is an acid therefore, it turns blue litmus paper red and red litmus paper remains red
Red litmus paper and blue litmus paper. Blue litmus paper turns red in the presence of an acid and red litmus paper turns blue in the presence of an alkali.
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.
Sour milk is acidic. Red litmus paper should not change.The sour part of sour milk is lactic acid. As litmus paper turns red when exposed to acidic compounds, litmus paper that is already red should not react when exposed to lactic acid.
yes a blue litmus paper turns red when put into an acid
blue litmus paper turns to red when its in contact with acid
Red litmus paper is used to check for basicity. It turns blue when exposed to bases. Blue litmus paper is used to check for acidity. It turns red when exposed to acids.
Turns red litmus paper blue.
HCl (hydrochloric acid) is an acid so it will turn litmus paper red. and alkali will go from red litmus to blue.
Red litmus paper remains red when dipped into an acid. Blue litmus paper will turn red in an acid. Similarly, Blue litmus remains blue in a base. Red litmus turns blue in a base.
Lemon juice is an acid therefore, it turns blue litmus paper red and red litmus paper remains red
Red litmus paper and blue litmus paper. Blue litmus paper turns red in the presence of an acid and red litmus paper turns blue in the presence of an alkali.
They turn it either red or blue. Acids turn blue litmus paper red and bases turn red litmus paper blue.
HCl (hydrochloric acid) is an acid so it will turn litmus paper red. and alkali will go from red litmus to blue.
When blue litmus paper touches an acid it becomes red. This is the type of litmus paper that detects acids. When red litmus paper touches an acid, it will remain red. This is used to test a base.
Acids turn blue litmus to red. Bases turn red litmus blue.
