What are common indicators are used to determine whether cargoes transported are acids or bases?
Common indicators used to determine whether cargoes are acids or bases include litmus paper (turns red in acids and blue in bases), pH paper (changes color based on the pH level), and universal indicator solution (changes colors to indicate the acidity or basicity of a substance). These indicators help in quickly identifying the nature of the cargo being transported.
Is an indicator's reaction in acids and bases a chemical change?
No, an indicator's reaction in acids and bases is a physical change. Indicators change color based on the pH of the solution they are in, but the chemical composition of the indicator remains the same.
What is difference between external and internal indicators used in titration?
Internal indicators that are used in titration exist in the titration reaction as either a reactant or a product. External indicators is added to the reaction mixture, but does not exist in the reaction.
Why is it that the presence of indicator does not affect reaction between acid and base?
Indicators do not interfere with the reaction between an acid and a base because they are typically weak acids or bases themselves. They only change color depending on the pH of the solution but do not participate in the acid-base reaction. This allows the reaction between the acid and base to proceed as normal.
Can an acid or base be detected with an indicator?
Yes, acids and bases can be detected with indicators. Indicators are substances that change color in response to pH changes, allowing us to visually determine if a solution is acidic, basic, or neutral. Common indicators include litmus paper, phenolphthalein, and bromothymol blue.

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 that you sit called when a dye that reacts chemically with acids and bases to produce one color acids another color bases?
These compounds are called pH indicators.
What is the name of the chemical that changes colour in acids and bases?
The chemical that changes color in acids and bases is called an indicator. Common indicators include litmus, phenolphthalein, and bromothymol blue. These substances change color in response to pH changes in a solution.
What will happen to the different indicators when dipped with acids and with bases?
When indicators are dipped in acids, they will change color to indicate acidity, usually turning red or orange. In contrast, when indicators are dipped in bases, they will change color to indicate alkalinity, usually turning blue or purple. This color change is due to the shift in the concentration of hydrogen ions in 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.
Can indicators change colour twice?
Yes.
Can an acid or base be detected with an indicator?
Yes, acids and bases can be detected with indicators. Indicators are substances that change color in response to pH changes, allowing us to visually determine if a solution is acidic, basic, or neutral. Common indicators include litmus paper, phenolphthalein, and bromothymol blue.
How do indicators distinguish acids and bases?
Indicators are substances that change color depending on the pH of a solution. They do this by undergoing a reversible chemical reaction that is sensitive to the concentration of hydrogen ions (H+) in the solution. In acidic solutions, indicators change color to reflect the acidic pH, whereas in basic solutions, indicators change color to reflect the basic pH.
