How indicators can tell the difference between acid and a base?
Indicators can differentiate between acids and bases based on their chemical properties. Indicators change color depending on the pH of the solution they are added to. For example, acids will turn indicators like litmus paper red, while bases turn them blue. This color change occurs because indicators respond to changes in hydrogen ion (H+) concentration in the solution.
Which 2 indicators turn the same colour with hydrochloric acid?
Methyl orange and methyl red both shows red color in a HCl solution where pH is lesser than 4.71.
Do acids turn indicator pink?
No, acids turn indicators red. Acids donate protons in solution, resulting in a color change in indicators from their normal color to red.
Does an acid or a base react with a predictable indicator to produce a color change?
Yes, acids and bases react with indicators to produce a color change, typically due to changes in the concentration of hydrogen ions (H+) in the solution. For example, indicators like phenolphthalein turn pink in basic solutions and remain colorless in acidic solutions.
Do acids have any effect on indicators?
Yes, acids can affect indicators by changing their color. Indicators are substances that change color in response to changes in pH levels, and an acid can cause this color change by altering the pH of the solution the indicator is in.
Why don't all acids turn indicators pink?
Not all acids turn indicators pink because the color change of an indicator depends on the pH of the acid. Different indicators have different color changes at different pH levels. Some indicators change color in acidic solutions, while others change in basic solutions.

What changes the color of indicators an acid or base or neither?
The color of indicators is changed by acids and bases due to their ability to alter the pH of a solution. Acids typically turn pH indicators like litmus paper red, while bases turn them blue. The specific color change depends on the type of indicator used, as different indicators have unique pH ranges for color changes. Therefore, both acids and bases can affect the color of indicators.
What is acid-base indicators?
These indicators change the color depending on the pH of the solution.
What are acid-base indicators?
Acid-base indicators, are chemicals that change color in response to acidic or basic conditions.
Which 2 indicators turn the same colour with hydrochloric acid?
Methyl orange and methyl red both shows red color in a HCl solution where pH is lesser than 4.71.
What are acid base indicators?
These indicators are substances which change their color depending upon acidity/basicity of the solution.
what acid-base change color when in contact with an acid or a base?
pH indicators change the color in contact with acids or bases.
Do acids turn indicator pink?
No, acids turn indicators red. Acids donate protons in solution, resulting in a color change in indicators from their normal color to red.
What will change color in the presence of an acid or a base?
pH indicators change the color depending upon acidity or basicity.
What are some indicators?
Indicators are chemicals that change color in the presence of an acid or a base. The most commonly used indicator is phenophthalein.
Does an acid or a base react with a predictable indicator to produce a color change?
Yes, acids and bases react with indicators to produce a color change, typically due to changes in the concentration of hydrogen ions (H+) in the solution. For example, indicators like phenolphthalein turn pink in basic solutions and remain colorless in acidic solutions.
