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.
What else can I help you with?
Is an indicator's reaction in acids and bases 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.
How do you calculate the theoretical pH of a solution?
To calculate the theoretical pH of a solution, you can use the formula pH -logH, where H represents the concentration of hydrogen ions in the solution. This concentration can be determined from the chemical equation of the reaction or by using the initial concentrations of the reactants. By plugging in the H value into the formula, you can find the theoretical pH of the solution.
Is mixing acid with base a chemical or physical change?
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.
How do you calculate buffer in a chemical solution?
To calculate the buffer capacity of a chemical solution, you can use the formula: Buffer capacity (moles of added acid or base) / (change in pH). This formula helps determine the ability of a buffer solution to resist changes in pH when an acid or base is added.
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.
Can a chemical reaction change the pH value?
Yes it can.
Could the change in the pH paper itself be a reaction Support your answer?
The substances contained in the pH paper react with the substance to be tested; and this is a chemical reaction.
Why is a indicator's reaction in acids and bases a chemical change?
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.
What is the indication that chemical reaction occurs between sodium hydroxide and acetic acid?
A change in the pH.
Is an indicator's reaction in acids and bases 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.
Is pH a physical or chemical?
pH is not a change at all. It is a chemical condition.
Why........Give a everyday example of a chemical reaction Describe the signs that a reaction has taken place?
* 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
Is there a chemical or physical change in a pH test?
It is a chemical change.

How can a chemical reaction be observed?
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.
