i think purple
Acid does not change the color of red litmus paper.
The litmus paper is turned to red color in acidic solutions.
HCl (hydrochloric acid) is an acid so it will turn litmus paper red. and alkali will go from red litmus to blue.
yes, it does, regardless of the substance colour.
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.
Red color in acidic solutions and blue color in basic solutions.
Acid turns it in red, while base will turn it blue.
They turn it either red or blue. Acids turn blue litmus paper red and bases turn red litmus paper blue.
No, only a base changes red litmus blue and not a acid.
isn't it red?? .....or is that in acids?.....
The litmus paper is turned to red color in acidic solutions.
Litmus paper is a substance that changes color in the presence of acids or bases. Acids turn litmus paper red, while bases turn it blue. By observing the color change, you can identify whether a substance is acidic or basic.
HCl (hydrochloric acid) is an acid so it will turn litmus paper red. and alkali will go from red litmus to blue.
When acids and alkalis are mixed, the pH of the solution changes. Indicators such as litmus paper will change color based on the new pH. Acids turn blue litmus paper red, while alkalis turn red litmus paper blue.
Blue litmus paper turns red in acid and stays blue in a base.
Yes, red litmus paper is an indicator that changes color in the presence of acids. In acidic conditions, red litmus paper will turn blue.
Blue litmus paper would be used and if the chemical is an acid the litmus paper would turn red.
Acids turn blue litmus to red. Bases turn red litmus blue.
