Yes it can.
To calculate the change in pH in a chemical reaction, you can use the Henderson-Hasselbalch equation. This equation relates the pH of a solution to the concentration of the acid and its conjugate base. By knowing the initial concentrations of the acid and base, as well as the equilibrium concentrations after the reaction, you can calculate the change in pH.
The substances contained in the pH paper react with the substance to be tested; and this is a chemical reaction.
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, 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.
A change in the pH.
* digestion is a chemical reaction.* Signs of chemical reactions may be: - Gas release - Formation of a precipitate - Change of color - Change of odor - Change of pH - Change of aspect - Change of viscosity - Change of the temperature - Visible formation of new compounds - Change of the state of the matter - A violent reaction with explosion or fire - Bubbling - Emitting a sound - Emitting a light
pH is not a change at all. It is a chemical condition.
It is a chemical change.
Some indications may be: - release of a gas - formation of a precipitate - change of color - change of odor - change of pH - change of viscosity - change of the aspect - etc.
Adding a base to an acid or vice versa in changing the chemical properties of that solution. In both cases you are neuralizing the solution. There might be a physical change as well, but it would depend on what chemicals where mixing. But this reaction will definitely have a chemical change.
When an antacid tablet dissolves in water, it is a chemical reaction. The tablet reacts with the water to neutralize excess stomach acid, which changes the chemical composition of both the tablet and the water.
Some signs for a chemical reaction are: change of the color, release of a gas, change of the temperature, formation of a precipitate, pH modification, viscosity variation, a change of the odor or taste, etc.
