because it has problems with itself
If if it is red Litmus paper, then it will remain red because vinegar is acidic. (Blue Litmus paper would turn red if you dipped it into vinegar).
it can turn red pH paper blue and blue pH paper red
HCl (hydrochloric acid) is an acid so it will turn litmus paper red. and alkali will go from red litmus to blue.
Because Vinegar is an acid, the litmus paper would turn red
it turns blue litmus paper 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.
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.
It remains red. Red litmus paper can only be used to test basicity, in which case it'll turn blue.
The litmus paper would stay red. That means vinegar is an acid.
yes you can, but your kitchen might not end up in one piece, haha!!
It depends on how you are planning to use it. Microwaving the vinegar is not recommended, as vinegar is expensive; microwaving a cup of water and then wiping can remove dirt inside a microwave cheaply. Moistening a cloth with vinegar and wiping the microwave may or may not work; vinegar works well on removing limescale, but that is an alkaline residue, so vinegar reacts with it. If I were you I would stick to recognised cleaning products or the cup of water method mentioned above.
