How do reagent strips change color?
Reagent strips change color by reacting with specific substances present in the sample being tested. This reaction causes a chemical change, resulting in a visible color change on the strip. The intensity of the color change can indicate the concentration of the target substance in the sample.
What should not be used to indicate a chemical reaction?
Change of shape can not be used to indicate a chemical reaction has happened. Examples of evidence of a chemical reaction are changes in odor or color.
What change in a physical property of matter can indicate?
A change in a physical property of matter can indicate a physical change, such as a change in state (solid to liquid), color, shape, or texture. These changes do not alter the chemical composition of the substance.
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 are four things that indicate that a chemical change probably happened?
Production of gas: If there is a sudden release of gas, bubbling, or fizzing, it may indicate a chemical change. Formation of a precipitate: A solid substance forming in a solution can indicate a chemical change has occurred. Color change: A visible change in color of the substance can be a sign of a chemical reaction. Change in temperature: A noticeable temperature change, either an increase or decrease, can be an indicator of a chemical change taking place.
Can a flower change in color?
Yes like when it dies or when it is growing.
Is change in color a clue that can indicate a chemical change?
Yes. Research litmus paper.
Does heat light and color indicate physical change?
i dont no the answer
When tiger fish get sick what color do they change?

When a bearded dragons dies does it change color?
not like the chameleon, but it might turn a bit black....
Does a color change indicate that something is soluble or insoluble?
A color change can indicate that a substance is soluble or insoluble, depending on the specific reaction. For example, some reactions may result in a color change when a soluble compound is formed, while other reactions may cause a color change when an insoluble precipitate is produced. The nature of the reactants and products involved in the reaction will determine whether the color change indicates solubility or insolubility.
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 are four things that indicate that a chemical change may have taken place?
Change in color: If the substance changes color during a reaction, it may indicate a chemical change. Formation of gas: Production of gas bubbles, fizzing, or bubbling is a sign of a chemical change. Temperature change: Significant heat or cooling effects can indicate a chemical reaction is occurring. Formation of a precipitate: When a solid substance forms in a solution, it suggests a chemical change has taken place.
