![Check Mark](/static/check-mark.png)
Interpretation:
Thebalanced equation and the solubility product constant of the given compounds are to be calculated.
Concept introduction:
The amount of solute dissolved in a given volume of the solvent to form a saturated solution at a given temperatureis termed as the solubility of the solute in the solvent at that temperature.
The solubility product of a sparingly-soluble salt is given as the product of the concentration of the ions raised to the power equal to the number of times the ion occurs in the equation, after the dissociation of the electrolyte.
The number of moles of the solute dissolved per litre of the solution is called molar solubility.
For a general reaction:
The solubility product can be calculated by the expression as:

- As you can see in the picture, the instrument uses a Xe source. Given that the instrument is capable of measuring from 200-800nm, if Xe was not used, what other source(s) could be used? Refer to figure 7-3. How many monochrometers does this instrument have? Why? Trace the light as it goes from the Xenon lamp all the way to the circle just slightly to the right and a little bit down from S4. What do you think that circle is? In class we talked about many types of these, which kind do you think this one is for a fluorimeter? Why? Explain. What is/are some strategy(ies) that this instrument has for dealing with noise that you see present in the optics diagram?
