A water sample is suspected to be contaminated by iron (III) ions. How could you determine if the sample is really contaminated?
if I have .42N NaOH and the stoiometry between Oxalic acid and Naoh is 1:2 then does that mean i do .42/.5=mol Oxalic acid * vol of titrations = molarity of oxalic acid
explain why nitration occurs more rapidly in a mixture of concentrated nitric and sulfuric acids than in concentrated nitric acid alone
The Ka of a monoprotic weak acid is 5.81 × 10-3. What is the percent ionization of a 0.147 M solution of this acid?
In the chemical formula for alu, there are 12 water molecules present. It is also possible to prepare the anhydrous compound potassium aluminum sulfate. On the "molecular scale" describe how a crystal of alum differs from a crystal of potassium al..
its freezing point depression constant is 8.37*C per molal. Use your corrected average temperature (5.0*C) to find the molality of the water in the alcohol. Find the percent water in the alcohol.

The process is mechanically irreversible, requiring 20% more work than the mechanically reversible compression and the sorroundings consist of a heat reservoir at 27 degrees C?
How could you convert butanenitrile into the following compounds? Write each step showing the reagents needed. (b) Butylamine and (c) 2-Methyl-3-hexanone
calculate the external pressure that must be applied to seawater, 1.14 M total ion concentration at 10 degrees celcius if the maximum concentration allowed in the product water
Calculate the enthalpy change associated with the conversion of 25.0 grams of ice at -4.00°C to water vapor at 110.0°C. The specific heats of ice, water, and steam are 2.09 J/g-K, 4.18 J/g-K, and 1.84 J/g-K, respectively. For H2O, Hfus = 6.01 kJ/m..
