PH mitric method for determination of stability constant?
Yes it can be determined by monitoring the change of the pH with time. Suppose you have a compound that is almost constant upto certain time but after some time the pH is getting decreased .So this is the point where your compound is degrading so at that pH calculate pKa and from there the stability constant.
What happens to the buffer a pH capacity?
The buffer maintain the pH constant.
Do the presence of an enzyme catalyst will affect the time taken for a reaction to reach equilibrium?
An enzyme catalyst will lower the amount of energy required to preform a reaction. This in turn, will make it much easier for the reaction to start. So yes, it will let a reaction reach equilibrium quicker. Other factors affecting the time of reaction are: The concentration of the reactants, (the less volume and more pressure you have will increase the rate of reaction) The PH level (especially important for biology reactions, protein enzymes are built for specific PH levels and will not work correctly if they are in another PH level, buffers can be used to stabilize pH levels)
If pH decreases by 1 pH number on the scale then how much has the concentration of hydrogen ions increased by?
If pH decreases by 1 unit on the pH scale, it means the concentration of hydrogen ions has increased by a factor of 10. For example, if the original pH was 7 and it decreases to 6, then the concentration of hydrogen ions has increased by 10 times.
What is a buffer in basic chemistry?
Buffers maintain a constant pH.
How can one determine the pH of a weak base?
To determine the pH of a weak base, you can use a pH meter or pH indicator paper. Alternatively, you can calculate the pH using the concentration of the weak base and its equilibrium constant.
What will happen to the pH if the temperature is increased?
Nothing if nothing evaporates.
What happens when reactant is added to a system at equilibrium?
The equilibrium of the system will be upset.
What would happen to urine pH if you increased secretion of hydrogen?
it would become more acidic
What is ion product constant?
Ion product constant is essentially when something reaches equilibrium. Such as in the case of water. When water reaches its ion product constant it becomes both a base and an acid, reaching equilibrium.

What will happen to the pH if you add base to water?
The pH of the water will increase, making it more basic. This is because the base will react with water to form hydroxide ions (OH-) which will increase the concentration of hydroxide ions in the water and shift the equilibrium towards a higher pH.
Does a weak acid ionize at pH 7?
A weak acid will partially ionize at pH 7, but the extent of ionization will depend on the specific weak acid and its equilibrium constant. The pH of a solution does not determine if a weak acid will ionize, but it can influence the degree of ionization based on the acid's pKa value.
What will happen when the pH of water when the co2 is removed from the water?
When CO2 is removed from water, the pH of the water will increase. This is because CO2 dissolves in water to form carbonic acid, which decreases the pH of the water. Removing the CO2 will shift the equilibrium towards fewer hydrogen ions, resulting in a higher pH.
What is the ph of rainwater in equilibrium with the atmosphere?
The pH of rainwater in equilibrium with the atmosphere is around 5.6, due to the presence of dissolved carbon dioxide which forms carbonic acid when mixed with water.
What is the process for calculating the pH of a weak base solution?
To calculate the pH of a weak base solution, you first need to determine the concentration of the base and the equilibrium constant (Kb) for the base's reaction with water. Then, use the equation pH 14 - pOH, where pOH is calculated using the concentration of the base and Kb. Finally, calculate the pH using the pOH value.
What products are formed when the aqueous ammonia is added to polyacrylic acid and and how to calculate the pH of the produced solution?
When aqueous ammonia is added to polyacrylic acid, the products are the ammonium salt of polyacrylic acid and water. To calculate the pH of the solution, you would need to consider the equilibrium between the acid (polyacrylic acid) and its conjugate base (ammonium polyacrylate). You can determine the pH based on the concentration of the acid, the equilibrium constant, and the dissociation of the acid.
