It would turn red in strong acid, orange/yellow in a weak acid, green in a neutral solution, blue in a weak base and purple in a strong base
An indicator used to detect an acid or base is a substance that changes color in the presence of acids or bases. Examples of indicators include litmus paper, phenolphthalein, and universal indicator solution.
The color of a universal indicator in a basic solution is usually purple or blue.
distinguish between common acid base indicator and universal indicator
difference between acid base indicator and universal indicator
A base typically turns universal indicator solution blue or purple.
Red cabbage or beetroot juice will do the job.
Universal indicator gives you an indication of the pH of the acid (i.e its 'strength') While both sulfuric acid and vinegar would turn litmus paper red, sulfuric acid would turn universal indicator red, pH of 1, while vinegar would turn it yellow-orange, pH of 4.
Recreation of an indicator using an acid and a base involves mixing a colorless or faintly colored acid-base indicator with an acid to make the solution acidic (and change color) and then adding a base to neutralize the acid and return the indicator to its original color. This process demonstrates the reversible nature of acid-base indicators and how they can be used to visually indicate the presence of acids or bases in a solution.
Yes it would
A pH indicator is a substance that changes color based on the acidity or basicity of a solution. It is often used in chemistry experiments to determine the pH of a solution. Common pH indicators include litmus paper, phenolphthalein, and universal indicator.
Yes, a strong base will turn universal indicator paper purple. Universal indicator paper changes color based on the pH of the solution it is exposed to, and a strong base will cause it to turn purple, indicating a high pH.
