How do you prepare 01M sodium borate -NaoH buffer pH 85?
To prepare a 0.1M sodium borate buffer at pH 8.5, you would first dissolve sodium borate (Na2B4O7) in water to achieve a 0.1M concentration, adjusting the pH to 8.5 using a strong base like NaOH. Keep in mind the pKa value of boric acid (the conjugate acid of borate) is around 9.2, so the buffer capacity may not be optimal at pH 8.5.
What is the PH of 0.001N NaOH?
The pH of a 0.001N NaOH solution is around 11.9. NaOH is a strong base, and at this concentration, it will result in a highly alkaline solution.
What is the pH of Pepsin in NaOH?
The pH of pepsin in NaOH would depend on the concentration of NaOH added. Pepsin is an enzyme that functions best at acidic pH levels, around pH 2.0. Adding NaOH, a base, would increase the pH, potentially inactivating the pepsin enzyme as it moves away from its optimal pH range for activity.
What is the pH of 0.5N NaOH?
The pH of a 0.5N NaOH solution would be around 14. NaOH is a strong base that dissociates completely in water to form hydroxide ions, which contribute to the high pH value.
What is the PH for 0.002M solution of NaOH?
The pH of a 0.002M solution of NaOH is around 11.98. This is because NaOH is a strong base that dissociates completely in water to produce hydroxide ions, which lead to the alkaline pH.

How much NaOH do you use to lower pH?
You dont - adding NaOH increases pH.
What is the pH of a 1 millimolar NaOH soluiton?
The pH of a 1 millimolar NaOH solution is approximately 11. The concentration of a 1 millimolar solution is 0.001 mol/L, and NaOH is a strong base that completely dissociates in water to produce hydroxide ions, leading to a basic pH.
What is the PH of 0.001N NaOH?
The pH of a 0.001N NaOH solution is around 11.9. NaOH is a strong base, and at this concentration, it will result in a highly alkaline solution.

What happens to the pH of distilled water when you add NaOH?
HCl : makes it acidic. it decreases the pH NaOH : makes it alkaline. it increases the pH
What is the PH for 0.002M solution of NaOH?
The pH of a 0.002M solution of NaOH is around 11.98. This is because NaOH is a strong base that dissociates completely in water to produce hydroxide ions, which lead to the alkaline pH.
What is the pH value of concentrated NaOH?
As NaOH is a strong base I would not be surprised to see a 14 pH at least.
What is the pH of 0.1m NaOH and 0.05m NaOH?
The pH of 0.1 M NaOH is approximately 13, as NaOH is a strong base that fully dissociates in water to produce hydroxide ions. The pH of 0.05 M NaOH would also be approximately 13, as the concentration of the base does not impact the basicity significantly when dealing with strong bases.
What amount of NaOH is needed to increase the pH from 8 to 10?
The amount of NaOH needed to raise the pH from 8 to 10 depends heavily on the conditions. The amount of NaOH needed will increase as the volume of the solution increases. Even more importantly, buffers can stabilize the pH significantly. If buffers are presently, the pH change will be much more gradual, and more NaOH will be required.
What is the pH of NaOH?
The pH of a solution of NaOH (sodium hydroxide) is approximately 14, as it is a strong base. This means it is highly alkaline.
