0.1 g of the mixture of na2so4 and k2so4 is taken and 100 ml of solution is prepared. 10 ml of this prepared solution is placed in a beaker and some distilled water is added. A mass of 15.5 mg is obtained by precipitation with Bacl2 at PH=5, then filtering and bringing to a constant weight at 800 °C. Calculate the percentages of Na2so4 and K2so4 in the mixture accordingly.

The analgesic aspirin is soluble at 25oC in water to the extent of 3mg/mL and in ethylacetate to the extent of 86 mg/mL. The approximate distribution coefficient of aspirin in these two solvents is __
The distribution coefficient of an organic salt between hexane and water is 90. A quantity of 0.1 mol of the salt dissolved in 100ml of water. Predict how many moles of the salt will remain within the aqueous phase following extraction by using four 25ml of aliquots of hexane to extract the salt from the aqueous solution
Sodium chloride (NaCl) was isolated from SiO2 and CaCO3 by dissolving it in distilled water. Unmentioned is that CaCO3 is slightly soluble in water (0.001 g/100 mL). Describe the effect this fact will have on each component of the mixture: will the “isolated“ mass of each be greater than, equal to, or less than that in the sample?
