When conducting a scientific experiment it is necessary to know that you have the correct concentration of the different chemicals involved. It is also important to be able to calculate concentration in order to determine how much of a reactant has been used up in a reaction or how much produ...
Learn how to calculate the concentration of a solute in grams per liter, and see examples that walk through sample problems step-by-step for you to improve your chemistry knowledge and skills.
a mathematical formula involving the initial concentrations of the two solutions, as well as the volume of the final solution, allows you to work out the final concentration in percent of the volume of the new combined solution.
If you’re ever wondering what streaming service you need to watch something (and the cheapest way to sign up for it), she’s your girl. Christina received a B.S. in Business Communication (concentration in writing) from Stevenson University and began her professional journey writing and ...
This "dissolving depth" depends on the concentration of calcium and carbonate already in seawater.碳酸钙溶解的深度取决于海水里钙离子和碳酸根离子的浓度。If the concentration is high, shells sink deeper before their calcium carbonate dissolves.如果浓度很高，壳将会在完全溶解之前沉得更深。And if the ...
Molarity is a familiar way to express concentration in chemistry. Take the number of moles, which is obtained from the molar mass, and divide by the number of liters. Normality takes into account reactive equivalents. The normality formula is N = Mn, wer
Chemistry Solutions What Are Solutions? How and Why Do Things Dissolve? Determining the Concentration of a Solution Factors That Affect Solubility Dilutions When making a solution, it's handy to know if one thing will dissolve in another. After all, if somebody wants you to make them a liquid...
Calibration curves are used in chemistry and other scientific disciplines often. A calibration is a pot of the concentration of known standards versus their signal. The signa could be measured in a variety of ways, such as absorption. The calibration curve...

Water is neutral, with a pH of 7; strong bases, 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 in moles, or individual particles (e.g...
