vinegar is a weak acid (acetic)
litmus turns blue in base (good mnemonic to remember - b=b)
pink in acid
If the solution contains acid, then the alkali turns the litmus to its original colour(blue).The color is effected by the concentration of the acid and the alkali.
In acid solution, blue colour of litmus is changed into red. In basic sol litmus change to blue.
soap is basic therfore, soap solution will keep blue litmus paper blue and turn red litmus paper blue
acetic acid has fewer H3O+ ions and hence it is weak acid . so it does not turn blue litmus to red .
a)sulfur dioxide b)hydrogen chloride c)potassium sulfate d)slaked lime
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.
Litmus paper turns red if the solution is acidic and blue if the solution is basic. Vinegar is an acidic solution (due to acetic acid), and will turn the litmus paper red.
it can turn red pH paper blue and blue pH paper red
The litmus paper would stay red. That means vinegar is an acid.
Litmus is used to test materials for their acidity. Blue litmus paper turns red when exposed to acid, so it would turn red when exposed to vinegar, which is acidic.

If you add red litmus paper and it remains red, then you add blue litmus paper and it remains blue, then the the solution is neutral. Kamal
Sodium chloride water solution is neutral.
If the vinegar is strong enough to be below 4.5 pH the litmus paper will turn (or stay) red.
It turns blue litmus red
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.
It turns blue.
