Assume you dissolve 0.235g of the weak acid benzoic acid, C6H5COOH. in enough water to make 0.01mL of solution and then titrate the solution with 0.108M NaOH.
(a) What was the PH of the original solution?
(b) What are the concentration of all of the following ions at the equivalence point?
Na+, H3O+, OH-, C6H5COO-?
(c) What is the PH of the solution at the euivalence point?
what is the concentration ratio of the free (and potentially toxic) Pb^2+(aq) in the blood to the much less toxic Pb^2+ -EDTA complex?
Draw resonance contributors for the following: indicate major and minor contributors to hybrid
Calculate the solubility product (Ksp) for silver bromide if the concentration of the silver ion is 0.770 M and of the bromide ion is 0.770 M.
meteorological balloon contains 375 L of helium at 29°C and 0.928 atm. If the volume of the balloon can vary according to external conditions, what volume would it occupy at an altitude at which the temperature is -40°C and the pressure is 0.031 a..
The enthalpy and entropy values are listed beneath each substance: 2 A + B ? 3 C + D ? Hf (kJ/mole) - 200 -50 -18 - 25 ? s (J/moleK) 25 40 300 75
when 0.625 g of ca metal is added to 200.0 ml of 0.500 m hclaq a temperature increase of 102c is observed. assume the
Calculate thePH at the equivalence point in titrating 0.100 M solutions of each of the following with 9.0×10^ 2 M NaOH... calculate the ph for HCLO2
a 368-g sample of water absorbs infrared radiation at 1.06x104nm from a carbon dioxide laser. suppose all the absorbed
Household ammonia, NH3 is a weak base. 10.00mL of ammonia was titrated with 0.1683 mol/L HCL 22.74 mL was required to reach the equivalence point. Calculated the PH after 0.00mL, 6.52mL, 11.37mL, 28.28mL, of hydrochloric acid solution are added.
Why is the E isomer of 1,2-dibenzoylethylene more stable than the Z isomer? is this why irradiation goes from E to Z and not the other way around? also discuss polarity differences between the two isomers.
Elementary mercury was first discovered when a mercury oxide was decomposed with heat, foarming mercury metal and oxygen gas. Wehn 0.24-g sample of the mercury oxide is heated, 0.189-g of mercury metal reamins.
added 5 mL of 0.10 M H2SO4 instead of 5mL 0.10 M of HCl calculate the ph of the solution using henderson-hasselbalch
