After some interval of time, the outer surface reaches at max concentration, however some part of material might be having very low concentration or no Li-ions at all. What I need to know is that " 1- What parameters are needed , as material properties? ( I know diffusion coefficie...
Generally, the exact concentration of the analyte must be known to achieve accurate results. The concentrations are usually expressed in units of moles per liter (mol/L). After the titration has been carried out, the concentration of the titrant, information from the balanced chemical reaction bet...
To set up a titration, you need an Erlenmeyer flask or 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 ...
Concentration of Solutions: Solutions can be formed by dissolving a solute with a solvent. The concentration of these solutions can be expressed in terms of the amount of solute with respect to the amount of the solvent or the solution as a whole. Answer and Explanation: 1 Become a Study....
determination of the concentration of the metal ions is that shall be drawn up at least two reference solutions of a different metal ion content, the following set and the same for each standard solution is measured quantity metalowska\\u017anika, uv vis spectrum absorbcyjne each standard ...
In this video, we learn how to study effectively in college. First of all, make sure you don't have an distractions around you. Find a place where you can study quietly where nobody will bother you and where you won't break your concentration. Find a way to study that works for you...
this additional information allows you to do the math in your head, and shows you the units they want. as discussed in the comments, a change in ph by one unit corresponds to a change in h+ ions by a factor 10. lower ph means higher h+ ion concentration. so you mu...
My question is, which one am I supposed to use to figure out the concentration? The products/rectants? The actual chemicals used or equation of reaction? Do I add all the chemicals/ions used and use a single concentration? And how exactly should I calculate the concentration?
i got question in an assignment where i have to design a method to find mass ratios of X to Cl in a substance XCl. (X is obviously a group 1 cation, eg K, Na, Cs, ect.). so the substance is one of a few things my thoughts on this is that I find out the weight of either...
It's because adding salt to your blood increases the solute concentration and lowers the osmotic pressure at the cell walls. The cells can't absorb the water and become dehydrated. If you drank only seawater, you'd actually die of thirst!
