If you mix 25.0 mL of .10 M methyl amine (CH3NH2 Kb= 3.6x10^-4) with 25.0 mL OF 0.10 M benzoic acid (C6H5COOH Ka = 6.3x10^-5), will the resulting solution be acidic, basic, or neutral?
Based on the procedure that you used in this experiment and using the same molar quantaties of reactants, develop a procedure that would be suitable for the preparation of isobutyl propionate.
In a coffee-cup calorimeter, 1.40 g of NH4NO3 is mixed with 79.0 g of water at an initial temperature of 25.00°C. After dissolution of the salt, the final temperature of the calorimeter contents is 23.23°C.
A sample that weighs 0.1586 grams contains only sodium chloride and potassium chloride was dissolved in water. It took 22.90 mL of 0.1000 AgNO3 to precipitate all of the chloride present.
