Ksp of Ca(IO3)2 lab questions 1) Why is it necessary to filter the calcium iodate solution through dry filter paper, without adding any water? 2) If water had been added during the filtration process, how would this affect your calculated value for the Ksp of calcium iodate? Clearly explain whether your value would be too high or too low compared to the actual Ksp and why.
You are given a sample containing a hydrocarbon and an amine both compounds are very insoluble in water and very soluble in diethyl ether. Describe how you could efficiently separate these two compounds using extraction methods; clearly explain why your procedure should give a good spearation of the compounds
5. Two wires from a battery are tested with a piece of filter paper moistened with aqueous NaCl solution. The solution also contained phenolphthalein, an acid-base indicator that is colorless in acid and pink in base. When the wires touch the paper about an inch apart, the rightmost wire produced a pink color on the filter paper and the leftmost produced no color. Write balanced half-reactions for what is happening at each electrode. Be careful! NaCl (ag) is only there...

How do you separate a mixture containing one water-soluble and one water-insoluble substance providing that the water insoluble particles are so small that it goes through the mesh of the filter along with the soluble?
2) The filter unit can remove 70% of turbidity from the source,Water The efflueht concentration of the turbidity is found to be 0.5 NTU Calculate the initial concentration of the turbid water? What steps are required to achieve 90% removal from this filter unit (2+3) (C1)
Design a lowpass filter, with cutoff frequencỵ 14 16 rad s w. The maximum gain of the filter should be A 17.46 dB, and the filter gain at angularfrequencỵws 3519 rad should be no more than As -21.99 dB. a) Give a detailed analytical solution, leading to your filter order, and circuit parameters Sketchan approximate bode plot of your filter's frequency response, using a straight line approxi- mation Can you solve the problem?

Calculate the % Al in the sample. Preparation of a stock solution of aluminum Accurately weigh out approximately 1 g of the aluminum foil. Tear it up into small pieces, place the pieces into a covered 250 mL beaker and add 60 mL of 6M HCl. This should be carried out in the fume hood because the reaction is exothermic and leads to violent frothing and emission of vapors. Cool, quantitatively transfer to a 250 mL flask, rinsing with deionized...
