Litmus paper.
The water solution of iodine turn blue litmus paper to red.
Red litmus paper does not change color when it rains; it remains red. Litmus paper is used to test pH levels, and rainwater is typically neutral to slightly acidic, which does not affect the color of red litmus paper. The color change occurs when red litmus paper is exposed to a basic (alkaline) solution, turning blue.
Red and blue are the two colors of litmus paper. Litmus paper is used to test the pH of a substance.
by using phenolphthalein,litmus paper (red and blue),cabbage,tea,and PH paper or PH meter
a litmus tells us if a substance is acidic or alkaline an acid will turn red litmus paper blue and an alkali will turn blue litmus paper red. if an unknown substance is tested with litmus and the colour did not change, then the substance is said to be neutral or it can be simply water. note that water is needed for acids to show its acidic properties........
Blue litmus paper would be used and if the chemical is an acid the litmus paper would turn red.
A litmus paper is a indicator that is used to test for acids or bases

Litmus paper is an indicator that changes color when affected by the pH of certain chemicals. There are two colors to test the general pH of a solution. Alkaline solutions (bases) turn red litmus paper blue. Acidic solutions (acids) turn blue litmus paper red.
The presence of acid can be detected by using an indicator such as litmus paper. Litmus paper turns blue litmus to red.
Methanol is a neutral substance and typically does not change the color of litmus paper. Litmus paper changes color in the presence of acidic or alkaline substances.
It depends. Litmus paper is used to test pH levels. Blue litmus paper turns red in the presence of acids, and red litmus paper turns blue in the presence of alkalines. Litmus paper is purple in neutral conditions.
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.
There are various ways to test for an acid and an alkali. For acidic solution: Litmus paper/ litmus solution --> red Phenolphthalein --> colorless Methyl orange --> pink Universal Indicator (changes color according to the strength of acid) --> red to yellow. For alkaline solutions: Litmus paper/ litmus solution --> blue Phenolphthalein --> pink Methyl orange --> yellow Universal Indicator --> blue green to purple
Alcohol does not significantly affect litmus paper. Litmus paper is primarily used to test for acidity or alkalinity in solutions by changing color, and alcohol does not typically cause a noticeable color change on litmus paper.
