A buffer solution is made using 1.0 M NH3 and 0.75 M NH4Cl.
A. What is the pH of the buffer solution?
B. What is the pH of the solution after the addition of 20.0 mL of 0.10 M NaOH to 100.0 mL of solution?
Calculate the concentrations of all ions in the solution after reaction. Check your concentrations to make sure that the solution is electrically neutral
A solution is prepared by mixing 20.0 mL of 0.025 M BaCl2 and 200. mL of 0.075 M K2SO4. What are the concentrations of barium and sulfate ions in this solution. Assume only SO42- ions (no HSO4? ) are present.
A student titrated 10mL aliquots of her unknown amino acid solution with standard 0.1521M NaOH and with 0.0986M HCl. Inflection points were determined in the graphs after 18.62mL of NaOH and after 3.29mL of HCl was added. What's the concentration ..
A student is asked to react 3-methyl-2-butanol with HBr. predict the products and explain why the experiment will not be as successful for production of an alkyl bromide as the reaction of 1-butanol with HBr
Fill in the lines for the orbital/arrow diagram for the valence electrons of the Dyprosium atom, including labeling the n, l and ml values and the individual orbitals that are known
You weigh 10 of the rings as well as find that they have combined mass of 7.38g; you then place them Ina graduated cylinder 2.5 cm in diameter as well as observe that the water level rises by 8.45 mm. Are the rings pure silver
What volume of carbon dioxide gas is produced after the complete combustion of 1L of methane gas?
What mass of H2 forms if 12 grams of Zn reacts with 7 grams of HCl?
How much energy is released during the complete combustion of 470 grams of cyclobutane
Question- NH3 is a weak base (Kb = 1.8x10^-5) and so the salt NH4Cl acts as a weak acid. 1) What is the pH of a solution that is 0.065 M in NH4Cl
Problem- We mix 50.00 mL of 0.050 M HNO3 and 25 mL of 0.10 M NaCH3COO. What is the pH of the resulting solution? Ka (CH3COOh)=1.8x10-5
In trans-1,2-dibenzoylethylene, even though the conjugated C=O group frequency coincides directly with the expected C=C stretching frequency, we would not have expected to observe the latter stretching mode in the infrared spectrum. Why
