Blue litmus is used to test acidic solutions.
Litmus is red at a pH under 4,5.
Purple litmus (neutral) become red in acidic solutions.
Acid turns blue litmus red and maintains red litmus at the same color.
Blue litmus paper will turn to red because hydrochloric is an acid. In aqueous solutions,acid change blue litmus paper to red. In aqueous solutions,base change red litmus paper to blue.
HCl (hydrochloric acid) is an acid so it will turn litmus paper red. and alkali will go from red litmus to blue.
Sulphuric acid turns blue litmus paper red, indicating its acidic nature.
red
Litmus is red at a pH under 4,5.
Litmus paper will turn red in sulphuric acid.
To distinguish between Sulphuric acid, Nitric acid, and Hydrochloric acid, you can perform a simple red litmus test: Sulphuric acid turns blue litmus paper red, Nitric acid bleaches red litmus paper, and Hydrochloric acid does not affect the color of red litmus paper. This test is based on their acidic properties and reactions with litmus paper.
A stench with a nicer color
Purple litmus (neutral) become red in acidic solutions.
One method to differentiate between sulphuric acid (H2SO4) and ethanoic acid (CH3COOH) is by using litmus paper. Sulphuric acid is a strong acid and will turn blue litmus paper red, while ethanoic acid is a weak acid and will also turn blue litmus paper red, but the color change may be less intense. Additionally, the two acids have different chemical formulas and properties.
Acid turns blue litmus red and maintains red litmus at the same color.
It will generally turn the litmus paper red.
The red litmus paper will remain red in acetic acid. Acetic acid is a weak acid and does not change the color of red litmus paper.
Acid turns litmus paper red.
