How many moles of H3O are present in an 85 L solution with a pH of 3.0?
To find the number of moles of H3O in the solution, you can use the formula pH -logH3O. First, calculate the concentration of H3O ions using the pH value: pH -logH3O 3.0 -logH3O H3O 10(-3.0) 1.0 x 10(-3) M Next, calculate the number of moles of H3O in the solution using the concentration and volume: moles concentration x volume moles 1.0 x 10(-3) mol/L x 85 L moles 8.5 x 10(-2) moles Therefore, there are 8.5 x 10(-2) moles of H3O present in the 85 L solution with a pH of 3.0.
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.
Is butter a neutral substance?
My guess, knowing something about the diary butter making process (charning acidified milk = buttermilk) is that the pH is somewhat lower than 5, not neutral anyhow, but slightly acid, though you can't taste it in the 15% water phase. pH in the 85% fat phase is not an issue because pH is defined for aquous solutions and acids do NOT ionise or protolyse in fat (hydrophobic). When butter becomes old and rancid the pH gets lower and is tastable!
What is the most acidic pH 10 pH 3 pH 2 pH 6 pH 8 pH 12 pH 1 pH 75?
pH 1 is the most acidic, as it is closest to 0 on the pH scale. Lower pH values indicate higher acidity.
How you can test the pH of solution?
You can test the pH of a solution using pH strips, pH meters, or pH indicator solutions. With pH strips, you simply dip the strip into the solution and compare the color change to a pH color chart. pH meters provide a digital pH value by immersing the electrode into the solution. pH indicator solutions change color based on the pH of the solution, allowing for a visual estimation of pH.

What temperature and pH do enzymes like to work at?
They like to work at or near body temperature with a pH of 7. Since there is a high concentration of water in cells and water's pH is 7, it makes sense that they like 7.
