Neutralization reaction equations for each of the strong acids HCl, HNO 3 and H 2 SO 4 with each of strong bases NaOH and KOH in aqueous solution should be written. Concept Introduction: When strong acid and a strong base are mixed together, the basic chemical reaction that occurs is reaction between H+ ions from the acid and OH- ions from the base to form water. The driving force for acid base reaction to happen is the formation of water. Other than the water, an ionic compound is formed which is known as a salt. Salt of strong acid and a strong base is also a strong electrolyte. So it completely dissociates in aqueous solution. Neutralization of acid and a base depicts that the pH of the final solution is 7. When a strong acid and a strong base are mixed in appropriate mole ratios, the final pH should be 7.

In the solid state, oxalic acid occurs as
a dihydrate with the formula H2C2O4
C+2H2O. Use this formula to
calculate the formula weight of oxalic
acid. Use the calculated formula
weight and the number of moles
(0.00504mol)
of oxalic acid in each titrated
unknown sample recorded in Table
6.4 to calculate the number of grams
of pure oxalic acid dihydrate
contained in each titrated unknown
sample.

Consider a pair of elements with 2p and 4p valence orbitals (e.g., N and Se). Draw their
(2p and 4p AO's) radial probability plots, and sketch their angular profiles. Then, consider these
orbitals from the two atoms forming a homonuclear л-bond. Which element would have a
stronger bond, and why?
