It can also be used to determine the concentration of hydronium or hydroxide ions, which can lead to determination of the concentration of other ions in the solution. You can use the pH equation below to perform the calculation to solve for unknowns. Hydrogen ions (H+) in aqueous solutions ...
Strong acids have low pH values. Water is neutral, with a pH of 7; strongbases, or proton acceptors (such as sodium hydroxide, NaOH) have high pH values, some close to 14.0. Moles and Molarity For acid-base chemistry purposes, it is more appropriate to measure solute concentration inmoles...
But a pH meter somehow has to measure the concentration of hydrogen ions. How does it do it? An acidic solution has far more positively charged hydrogen ions in it than an alkaline one, so it has greater potential to produce an electric current in a certain situation—in other words, it...
If you want to perform imaging of adherent cells, such as to undertakecancer cell microscopy, you need to fix them to your microscope slides. Luckily for you, this is fairly easy to do, thanks to the fact that adherent cells are, well, adherent, and like to grow on plastic or glass—...
The solubility product constant of Calcium hydroxide is 6.5 times 10^{-6}. If 0.10 mol of sodium hydroxide is added to 1 L of 0.0001 M Ca(OH)_2, what is the final concentration of the calcium ion? What is the molar solubility of calcium carbonate, CaCO_3...
Osmotic pressure is a pressure applied to stop osmosis. Osmotic pressure is calculated by multiplying the vant Hoff factor, the molar concentration of solute in the solution, the universal gas constant, and temperature.Answer and Explanation: ...
Be aware that your filtration unit’s effectiveness depends on several factors, though, “like concentration [of PFAS] in the incoming water, and other contaminants, like heavy metals, organic matter, [and] other ions ... so you have several factors that all play into the overall efficiency,...
Solid barium sulfate is placed into a beaker to form a saturated solution of barium sulfate. The solution has a barium concentration of 1 x 10^{-5}M. What is KSP for barium sulfate? What is the precipitate formed when BaCl_2 and Na_2SO_4 are mixed? \ A.\ NaCl\ B.\ BaCl_2\ ...
A strong base, on the other hand, has more hydroxide ions than hydrogen ions. Let's say that you have a 0.1M solution of NaOH. What is the concentration of H+in this case? Now, you're going to need to use your knowledge of KW. ...
beaker, an excess amount of solution of known concentration (titrant), a precisely measured amount of analyte (used to make the solution of unknown concentration), an indicator, a calibrated buret (a glass device that allows the precise delivery of a specific volume of solution) and a buret ...
