1. List all the strong aqueous acids. What is the difference between a strong acid and a weak acid? How do the concentrations of the strong and weak acids compare to the H3O+ in solution? You don't need to list all of the strong aqueous acids. I am guessing strong acid has more hydrogen ions? 2. What is pH? What happens to pH as the [H3O+] increases? Support your answer by comparing the pH of 0.50 M and 0.050 M HCl. For this one I know ph is the measurement of the acidity/baic of the solution 3. Why is the pH of basic solution greater than 7.0 while that of acids is less than 7.0? Would the pH of a 0.1 M weak acid be greater than or less than that of a 0.1 M strong acid ? 4. If the measured pH of a 0.10 M weak acid, HA, is 2.45, what is its experimental Ka value. 5. Give examples of a neutral salt, acidic salt and basic salt. Explain your choice.
Based on the principle of "like dissolves like", indicate the compounds listed below that are likely to be soluble in an organic solvent like methylene chloride or diethyl ether and those that are soluble in water.
At 30°C, by how much is a reaction's activation energy decreased by the addition of a catalyst if the catalyst triples the reaction rate?
Cinnamon owes its flavor and odor to cinnamaldehyde (C9H8O). Determine the boiling point elevation of a solution of 89.3 mg of cinnamaldehyde dissolved in 1.00 g of carbon tetrachloride (kb = 5.03 C/m)
The total pressure in an 12.4L automobile tire is 42psi at 15 degrees Celsius. how much does the pressue in the tire rise if it warms to a temperature
A 0.1019g portion of an aspirin tablet was dissolved in sufficient water to prepare 1.000L of solution. A pipet was used to transfer 10 mL of the solution to a 100 mL volumetric flask.

When ammonia is added to nickel ions in aqueous solution, the water molecules bound to the Ni2+ are replaced by ammonia molecules.
A 65.00 mL sample of HNO3 solution is neutralized by exactly 34.16 mL of 0.5841 M Ba(OH)2. What is the molarity of the HNO3 solution?
In what order would the amino acids arginine, leucine, and lysine be eluted from a Dowex-1 column at pH 10.5? (b) In what order would glutamic acid
In an experiment you combine 4-methyl-2-pentene and water, in the lab you setup the experiment using a a heater, condenser and N2 gas and add the reagent H2SO4
A titration of 200.0 mL of 1.00 M H2A was done with 1.10 M NaOH. For the diprotic acid H2A, Ka1 = 2.5 × 10-5, Ka2 = 3.1 × 10-9. Calculate the pH after 600.0 mL of 1.10 M NaOH have been added.
