Is denture cleaner tablet a chemical or a physical change?
When a denture cleaner tablet dissolves in water to form a cleaning solution, it undergoes a chemical change. The tablet breaks down chemically to release cleaning agents that interact with the water molecules to clean the dentures.
What liquid solution becomes red in an acid?
Phenolphthalein solution turns red in an acidic environment. This color change occurs due to the shift in the pH of the solution, which causes phenolphthalein to undergo a chemical transformation and display a red hue in acidic conditions.
Why does phenol red change yellow?
Phenol red changes yellow in acidic conditions due to a shift in its chemical structure, which occurs when the hydrogen ions in the solution cause the indicator to undergo a color change. This change is reversible when the solution becomes basic again.
A solid brown metal is added to a clear acid solution A white powder appears and the acid solution becomes cloudy Which types of change havehas occurred?
only chemical
Is mixing sugar with iodine solution a chemical change or a physical change?
Mixing sugar with iodine solution is a physical change because no new substances are formed. The sugar and iodine solution retain their individual chemical properties even when mixed together.
Does a solution have a chemical change?
A solution does not have a chemical change, but it does have a physical change in state.
Is denture cleaner tablet a chemical or a physical change?
When a denture cleaner tablet dissolves in water to form a cleaning solution, it undergoes a chemical change. The tablet breaks down chemically to release cleaning agents that interact with the water molecules to clean the dentures.
Is making salt crystals on a pipe cleaner with water and borax a chemical change?
This is not a chemical change.
Is this a chemical change or physical change silver nitrate solution is added to another solution producing a white solid?
it is a chemical change

If a chemical reaction occurs in a solution and the solution becomes warmer?
If a chemical reaction occurs in a solution and the solution becomes warmer, it indicates that the reaction is exothermic. This means that energy is being released in the form of heat as the reactants are converted into products. The increase in temperature can be measured and serves as evidence for the energy change occurring during the reaction. Such reactions often involve the breaking and forming of chemical bonds, releasing energy stored in those bonds.
Why does phenol red change yellow?
Phenol red changes yellow in acidic conditions due to a shift in its chemical structure, which occurs when the hydrogen ions in the solution cause the indicator to undergo a color change. This change is reversible when the solution becomes basic again.
How is rotting a chemical change?
garbage rotting is a chemical change because the odour becomes different which is considered a sign of chemical change.
When a solution is heated and a gas is formed is that a chemical change?
If there is no chemical reaction occurring in the solution as a result of heating then this scenario constitutes a phase change.
How chemical change that garbage undergoes?
garbage rotting is a chemical change because the odour becomes different which is considered a sign of chemical change.
