Do acids effect indicators?
Yes, acids can affect indicators by changing their color. Indicators are substances that change color in response to the acidic or basic nature of a solution. Acids can cause indicators to change color depending on their pH level.
Why does a chemical reaction which have occurred between acids and bases change color?
The change in color in this type of chemical reaction is due to the formation of a new substance with different chemical properties. This new substance may absorb and reflect light differently, leading to a change in color. This phenomenon is often used in indicators to visually show the endpoint of an acid-base reaction.
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.
Is reaction with acid a physical or chemical property?
A physical reaction is when no new substances are formed, there is a change of state eg ice melting to a liquid. A chemical change is when the reaction forms a new substance. eg gas bubbles. An acid reaction can be both. You need to look at the reaction taking place, look for change of state (physical) or any colour change or gas bubbles (chemical).
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.
Is an indicator's reaction in acids and bases a chemical or physical change?
The indicator's reaction in acids and bases is a chemical change because it involves a change in the chemical structure of the indicator molecule due to its interaction with the ions present in the acid or base solution. This results in a change in color, which is a visible manifestation of the chemical reaction taking place.

What chemical an you use to test acids and alkali's?
These substances are called pH indicators.
When acids are added to rocks containing a carbonate bubbles form is this evidence of a physical change or chemical change?
This is evidence of a chemical change. When acids react with carbonate minerals in rocks, they create gas (CO2), which leads to the formation of bubbles. This reaction results in the formation of new substances, indicating a chemical change.
How is toasting bread chemical or physical change?
Toasting bread is a chemical change because the heat causes a chemical reaction in the bread, leading to the browning and change in flavor. This involves the Maillard reaction, where the sugars and amino acids in the bread react to form new compounds.
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.

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.
How is frying an egg became chemical change?
When the egg is in its liquid form and then heated, a chemical reaction between the protein and amino acids cause it to harden therefore making your "Became chemical change"
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.
