As methyl orange is slightly acidic, it turns 'moist' blue litmus into red.
The colors of litmus is different; this depends on the pH.
Blue litmus paper turns RED in an acid. Red litmus paper turns BLUE in a base.
Blue litmus does not change when placed in a basic solution.
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 vinegar solution because vinegar is acidic and pH below 7. The acidic solution causes the blue litmus paper to undergo a color change and turn red.
yes a blue litmus paper turns red when put into an acid
It turns blue
When blue litmus paper is placed in soapy water, it remains blue because soap is typically alkaline (basic). Litmus paper is used to test pH levels, and blue litmus paper indicates a neutral or basic environment. If the water were acidic, the blue paper would turn red, but in this case, the soapy water keeps it blue.
wel, i hav performed this experiment and actually used blue and pink litmus papers. blue litmus turned pink and pink remained pink when subjected to vapors emerging from the mouth of the test tube being heated. i hope this helps...
As soap is alkaline in nature, it turns red litmus paper blue
It turns blue.
Blue litmus paper will turn red when dipped in dilute nitric acid. This color change indicates that the solution is acidic. Nitric acid is a strong acid and will donate protons to the litmus paper, causing the color change.
