Problem- Calculate the change in pH when 9.00 mL of 0.100 M HCl(aq) is added to 100.0 mL of a buffer solution that is 0.100 M in NH3(aq) and 0.100 M in NH4Cl(aq). Calculate the change in pH when 9.00 mL of 0.100 M NaOH(aq) is added to the original buffer solution.
Answer showing how to make each solution will get rated
what is the final temperature of the mixture? Use 1.00g/mL as the density of water.
In this experiment the choice of precipating reagent is important. briefly explain what the consequences would be if excess 6M NaOH solution instead of 6M NH3 solution were used to seperate Fe3+ and Al3+ ions from Ca2+, Cu2+, and K+ions at pH9-10...
Draw the structure(s) of the ketones with the molecular formula C6H12O that have a four-carbon chain.
Problem- Part 1) What spectroscopic technique would you use to distinguish between cyclopentane and cyclohexane. Briefly and succinctly explain how this technique would enable you to do this.
a sample of a mixture of cac2o4 and mgc2o4 was dissolved in about 100 ml of aqueous acid. one half of the solution was
A 2.30-g sample of a large biomolecule was dissolved in 22.0 g of carbon tetrachloride. The boiling point of this solution was determined to be 77.85°C. Calculate the molar mass of the biomolecule.
In some industrial processes, sulfite is added to remove dissolved O2 to prevent corrosion of pipes. Write the balanced overall chemical reaction for reduction of dissolved O2 by sulfite (SO32-).
Explain why bubbling a solution with an inert gas such as argon or nitrogen causes deoxygenation of the solution?
Determine the mole fractions and partial pressures of CO2, CH4, and He in a sample of gas that contains 1.25 mole of CO2, 1.59 moles of CH4, and 3.41 moles of He, and in which the total pressure is 5.78 atm.
solid NaI is slowly added to a solution that is 0.010 M in Cu+ and 0.010 M in Ag+. which compound will begin to precipitate first?
A solution is made by dissolving 0.687 mol of nonelectrolyte solute in 797 g of benzene. Compute the freezing point and boiling point of the solution. Constants may be found here.
What is the enthalpy of this reaction. Assume that no heat is lost to the surroundings or to the coffee cup itself and that the specific heat of the solution is the same as that of pure water.
