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.

What four properties that acids and bases have in common?
Both acids and bases are electrolytes, meaning they can conduct electricity in solution. They can react with each other to form water and a salt. Acids and bases can change the color of certain indicators to show their pH levels. Acids and bases can neutralize each other when mixed in the right proportions.
Which of these properties is common to both acids and bases?
Both acids and bases can be categorized as electrolytes, meaning they can conduct electricity when dissolved in water. Additionally, they both can react with certain metals to produce hydrogen gas. Lastly, both acids and bases can change the color of specific indicators to indicate their presence.
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.
What are some names of natural indicators and how do they detect acids and bases?
Some natural indicators include red cabbage, turmeric, and blueberries. These indicators change color in the presence of acids and bases due to their chemical properties. For example, red cabbage contains a pigment that changes from red in acids to green/blue in bases.
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.
How many indicators distinguish acid and bases?
About 10 distinguish Acids and bases. ( written by and 11 year old)
What is used to indentifiy bases and acids?
Acid base indicators are used to identify acids and bases. Among the common indicators are;PhenolphthaleinMethyl redMethyl orangeBromothymol blue
What is a compound that react with acids and bases to make certain colors?
Indicators are compounds that react with acids and bases to make certain colors. (:
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 household materials make good indicators for acids and bases?
red cabbage is a good indicator
How can I distinguish between bases and acids by methods other than using litmus paper?
there are other indicators that can be used - universal Acid-red Base-Blue Neutral-green methyl orange Acid - red Base - yellow
What is used to determine the presence of acids and bases by a change in color?
Acid-base indicators are used for this purpose.

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.
