The pH scale ranges from 0 to 14 under usual conditions and measures the acidity of an aqueous solution. This is derived from the molarity of protons (hydrogen ions, or H+) in the solution. To find pH for a given molarity, you need to know how to work wi
Sorry, but this is a random number, not even closely related to what you are trying to find.The only way to check the solution concentration from your measurement is to calculate the density (you have both mass and volume), and find the related concentration in the density tables. Okay ca...
Titration is used to determine the concentration of an unknown substance via the molar relationship expressed through the chemical reaction equation. Using these relationships, the pH value can be determined by calculating the concentration of hydrogen i
Nitrogen-fixing bacteria employ different strategies in order to maintain low intracellular oxygen concentrations. Rhizobia take advantage of the low oxygen concentration inside the plant roots where they fix nitrogen. Azotobacter vinelandii cells have a high concentration of respiratory complexes and ...
We did not find that rising concentration slowed productivity growth in our sector cases, but this may not be the case in the future if changes in industry structure reduce competitive intensity as well as incentives to innovate and improve operational performance. While the economic cost associated...
“We’re in sort of the primordial ooze of how A.I. is going to find its way,” says Gordon Ritter, founder of venture firm Emergence Capital and an investor in several A.I. startups. “Is it friend or foe?” Ritter is betting that A.I. will prove beneficial, but for now, to...
I have a 2-D dynamic diffusion problem. I would like to know how to compute the average concentration over the 2-D subject? Thanks in advance, Xin 5 Replies Last Post 2011年3月9日 GMT+8 02:42 Ivar KJELBERG COMSOL Multiphysics(r) fan, retired, former "Senior Expert" at CSEM SA ...
Steps for How to Calculate pH of Salt Solutions Step 1: Read through the given information, and determine if the salt comes from a weak acid or weak base. Step 2: Write the hydrolysis reaction that comes to equilibrium Step 3: Tabulate the equilibrium conditions in terms of x. Step ...
"Some parents think that the student must go to a four-year school, but we know that's not necessarily the right journey for all," Cook says. Pringle notes that services for students who are struggling academically often go underused. ...
whereas a low pH (high H+concentration) has the opposite effect. Other amino acids will accept H+from the solution and therefore change to having a positive charge as the pH falls. In order for enzymes to function a proper balance of these charged amino acids needs to be present. That ba...
