The pH gives you an indication of the concentration of H3O+in the solution while the pOH gives you an indication of the concentration of OH-. But how do you actually get these numbers, and what do they mean? How Do You Calculate pH and pOH? The "p" in pH and pOH indicates "-log....
Calculate the pH, pOH, and percent deprotonation of .20M CH3COOH. Ka=1.8x10^-5. A buffer is prepared by mixing 50.3 mL of 0.183 M NaOH with 138.1 mL of 0.231 M acetic acid. What is the pH of this buffer? (The pKa for acetic acid is 4.75.) Calculate the pH of this buffer aft...
If a 1.0L solution has an initial pH of 6.70 how much KOH do i need to add to get a desired pH of 6.80? The solution will react 1:1 with the KOH: H+ + OH- --> H2OFollow • 1 Add comment 1 Expert Answer Best Newest Oldest Michael M. answered • 06/30/...
It is often said that there are three methods or ways to calculate aircarft weight and balance, but that’s not entirely true. All of these “methods” are based on calculating the weight and balance with a simple math formula. A better way of saying it is that your POH or AFM will ...
Calculate the molarity of a solution containing 10.0 grams of H2SO4 and 800.0 mL of water. Also, solve for pOH and pH. If 40 mL of sulfuric acid is needed to neutralize 22 mL of 0.6 M Ca(OH)_2, what is the concent...
determine whether you enter the angle (check the units) and then sin, cos, tan, etc., or whether you press the sin, cos, etc., button and then enter the number. How do you test this: Remember the sine of a 30-degree angle is 0.5. Enter 30 and then SIN and see if you get ...
Now, there’s many kinds and levels of AI, and people confuse these and conflate them. The first kind of AI is just computers doing stuff that we try to do in our minds, like calculate what a parabola is, how fast a car is going to go, or how much money a bu...
Water Discount:A factor in a soap recipe where less water is used than is recommended within a safe recipe. A water discount reduces cure time but can also lead to a false trace or seizing within the pot. Do not calculate in a water discount if you are just learning how to make ...
Nevertheless, it is clear that over the past century the residential standard of the Dutch has risen considerably, and we expect it to do so in the future. Second, in European countries, the location choices of the rich are driven by the presence of (natural) amenities rather than by the...
