Do acids turn blue litmus paper red?
Yes, acids will turn blue litmus paper red. Litmus paper is a pH indicator that can detect the presence of acids and bases in a solution. Acids, which have a low pH, will react with litmus paper and change its color from blue to red.
Yes, acids turn blue litmus paper red. Litmus paper is a commonly used pH indicator. It is an absorbent paper that has been treated with a specific dye derived from lichens. Blue litmus paper is blue in its base form. When it comes into contact with an acid, such as hydrochloric acid or vinegar, the acid reacts with the blue dye, causing the litmus paper to turn red. This reaction is due to the pH change caused by the acidic property of the substance.
Yes, acids turn blue litmus paper red. Litmus paper is a commonly used indicator paper that changes color depending on the pH (acidity or alkalinity) of a substance. It is usually blue in its natural state, but it turns red when exposed to an acidic solution.
To understand why acids turn blue litmus paper red, let's look at the chemistry behind it. Litmus paper contains a dye called litmus, which is extracted from lichens. Litmus is a weak acid that changes color depending on the concentration of hydrogen ions (H+) in a solution.
When an acid is added to blue litmus paper, the hydrogen ions in the acid react with the litmus dye. This reaction causes the litmus dye to undergo a color change, turning it from blue to red. This color change indicates the presence of an acidic solution.
It's important to note that litmus paper is not specific to a particular acid. It simply indicates whether a solution is acidic or basic. Other indicators, such as pH paper or pH meters, can provide more precise measurements of pH levels.
