Salt; Precipitation
The solid that forms out of a solution is called a precipitate. It is formed when the solubility limit of a substance in a solution is exceeded, causing it to separate out as a solid. This process is known as precipitation.
When an indicator is added to an acid or base, it undergoes a chemical reaction with the hydrogen or hydroxide ions present in the solution. This reaction causes a change in the color of the indicator, indicating a shift in the pH of the solution. Since a new substance with different properties is formed during this reaction, it is considered a chemical change.
No, the number of particles of a substance is determined by the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. The number of particles remains the same before and after the reaction.
When you mix borax solution with glue, a chemical reaction occurs where the borax molecules crosslink the polymer chains in the glue. This leads to the formation of a new substance with different properties compared to the original glue and borax solution, constituting a chemical change.
It is Precipitation
The heat of solution refers to the heat energy absorbed or released when a substance dissolves in a solvent, while the heat of reaction refers to the heat energy absorbed or released during a chemical reaction. The heat of solution can be a part of the overall heat of reaction if dissolution of a substance is involved in the chemical reaction.

The term for an insoluble solid substance produced from a reaction in aqueous solution is a precipitate. This forms when the ions in the solution react to form an insoluble compound that falls out of solution.
The solid that forms out of a solution is called a precipitate. It is formed when the solubility limit of a substance in a solution is exceeded, causing it to separate out as a solid. This process is known as precipitation.
A titration reaction is a chemical technique used to determine the concentration of a substance in a solution. It involves the gradual addition of a known concentration of another substance, called the titrant, to the solution until a reaction is complete. The endpoint of the reaction is usually detected using an indicator or an instrument, allowing for the calculation of the concentration of the unknown substance.
This could refer to a chemical transformation (chemical change), a chemical reaction, or spontaneous change. Some changes require another substance or substances to be mixed together. Some reactions will occur by themselves without any outside manipulation or stimulation.
first when there's a physical change in the substance second there will be a solution or a formula to that substance third is, it involves temperature fourth is change in color of the substance fifth is the bubbling of another substance is yet an another clue that a chemical reaction has occured.
a catalyst
if the solution has undergone a chemical reaction and a solid forms, that solid is called a precipitate.
