If you think of Raoult's law as a special case of Henry's law (since in both cases the vapor pressure of a substance is proportional to its mole fraction in solution) then there isn't really a problem. The case you describe where the solute concentration in solution spans the range $\chi=0-1$ and observes the equation $$\chi=\frac{p}{K}$$ where $K$ is equal ...

(Source: chem.libretexts.org) In the image, we see that for a "real gas" (indicated by non-ideal solution), Henry's law is applicable for $\ce{\chi} << 1$. As, $$\ce{p = K_H \cdot \chi}$$ hence the pressure should be low. Limitations of Henry's law: The pressure should be low and the temperature should be high i.e the gas should behave like ...

Glass syringes and glass pipettes are high precision and high accuracy tools of an analytical chemist. Like any tool at home, such as a cloth cutting scissor and a plant pruning clipper do the same job of cutting but their applications are different. As an analytical chemist, I have not seen anyone using microsyringes for standard preparations in volumetric ...

It will be the same, but only if molar fractions of liquid and gaseous phases in the first system are the same. By other words, only if the 1st system contains an azeotropic mixture.(.and therefore the 2nd one as well ) Unless a mixture is an azeotrop ( vapours have the same composiotion as liquid ), or by chance the components have the same boiling point ...

Rosin acids, or more commonly, resin acids, are more complicated structures that are able to protect an air bubble mechanically. Abietic acid, a common resin acid, looks like a platey structure with more strength than a linear chain like stearate or oleate, two other common soap anions. In fact, resin acids were, and still are, used very commonly to ...

This is where your logic fails: since the concentration of reactants and products remains the same since B is different from A As soon as you mix two components you change the concentration of both, you effectively dilute all components. Otherwise your intuition is correct. The gases can often be assumed to act independently. This is true if the solution ...

Equivalent concept is an archaic unit of measurement that was used in chemistry and the biological sciences in the era before researchers knew how to determine the chemical formula for a compound. An equivalent (symbol: officially equiv; unofficially but often Eq) is the amount of a substance that reacts with (or is equivalent to) an arbitrary amount of ...

Thank you everyone for the discussion. Sorry, I have been away for a few days, so was unable to follow up. Reading the ideas, it is a toss up on a procedure. Scraping the Cd off of an Aluminum electrode might work, but Al contamination would be very bad for the laser oscillation. It might work for awhile, but would die from contaminants in short order. ...
