I learned at some point how to do pH-calculations, but my teacher was so bad, that I never really understood it and now I don't manage to calculate it myself anymore Maybe someone here could help me with the following?Have 8 liters of watery solution with pH of 7.4 and want to adj...
You may be, I was, surprised that the difference between the calculations is even as much as Borek says, but the difference I think is only about 5X10-8 M in [H+]. I think it would be difficult to make up that solution to give you the pH to 0.02 units. ) The second problem I...
How do you do titration calculations? Titration Procedure Titration is a method to determine the concentration of a substance. A known amount of the solution is pipetted into a flask. A pipet is a long tube that can measure volume very accurately. A solution of known concentration which react...
I've found a couple of examples on how to calculate the x/y coordinates of the four corners of a rotated square or rectangle using the radians of the rotated angle and cos and sin. But because geometry isn't my strong suit I don't know how these calculations would apply to ...

Use an existing library known to handle the quirks involved in dealing with time calculations. My current favorite is moment.js. var now = moment(); // get "now" console.log(now.toDate()); // show original date var thirty = moment(now).add(30,"minutes"); // clone "now" objec...

I'm doing an experiment where I measure the pH, then do a few calculations to get to the pKa value. But for this experiment, I need to include the uncertainties. The uncertainties for things like mL, temperature, etc, are simple enough, and I can do them, but I'm unsure of how to...
Here are some example calculations and how to determine the correct way to enter them. Whenever you borrow someone's calculator, get into the habit of performing these simple tests to make sure you're using it correctly. Square Root:Find the square root of 4. You know the answer is 2 (...
