Intrinsic Solubility Question:
Make a 100ml of 1M homogeneous solution of acetaminophen (weak acid).
Molecular weight = 151.16 g/mol,
Solubility = 1.278%w/v,
pKa = 9.51.
Identify the S0, Si and St parts in this solution. What will be the pH of this solution?
Problem- A by-product of Ethane C2H6 oxidation by O2 is acetaldehyde C2H4O. Acetaldehyde then produces a chemical called peroxyacetal nitrate or "PAN" (C2H3O3NO2), a nasty eye irritant.
which effect on atomic size is more significant, the nuclear charge (p+) or the energy level that the eleectrons are filling explain why.
What is the pH of a 0.15 M solution of aqueous Acetic Acid. The Ka of acetic acid is equal to 1.7 x 10^-5
Why does G always decrease as you move towards equillibrium no matter what concentrations of product and reactant you start with. or does it always decrease
The molar heat of neutralization from hydrochloric acid and sodium hydroxide is -57.3 kJ/mol. use this accepted value to predict the heat evolved
Which of the subsequent statements correctly explain thehydronium-hydroxide balance in a given solution
Explain how would value for equivalence weight be affected if some of the H2 gas produced all through the reaction of Mg(s) and acid escaped from gas brute
the meta and para forms of phenylene diamine are used in the production of Kevlar and Nomex, respectively. Why is a corresponding material with similar properties not made from ortho-phynelene diamine
The buret continues to drain, slowing gradually until coming to a complete stop, as depicted on the right side. At that moment, the total pressure of the gases inside the flask just equals the total pressure of the atmosphere plus the additional p..
The formation constant of a complex ion [M(NH3)4]2+(aq) is 3.8E8. If a solution is prepared by adding 0.6 mol of [M(NH3)4]Cl2 to 275.0 mL of water, what is the equilibrium concentration of free M2+(aq) ions?
Ascorbic acid, HC6H7O3, also known as vitamin C, is a weak acid. It is an essential vitamin and an antioxidant. A solution of ascorbic acid is prepared by dissolving 2.00 grams in enough water to make 100.0 mL of solution
Problem- Calculate the molarity of a sodium hydroxide solution if a .5356g sample of KHP was dissolved in 50 ml of water and titrated with 20.78 ml sodium hydroxide to a phenolphthalein endpoint.
