PROCEDURE: When copper(II) sulfate x hydrate, a blue crystalline solid containing embedded water molecules (called a hydrate), is heated in air, it loses the water molecules and the blue solid is transformed to a white anhydrous (no water) crystal known as anhydrous copper(II) sulfate. The "x" represents a whole number of water molecules attached to...

1. Hg(OAC)2, H20 2. NaBHg CH3 H3C H₃C Acid-catalyzed addition of water to an alkene yields an alcohol with Markovnikov regiochemistry. The electrophilic add carbon with the most hydrogens to yield the most stable carbocation intermediate, which then adds water to give the produc Because a carbocation intermediate is formed, rearrangements can occur prior to the addition of water. To avoid the possibility of rearrangement and still give a Markovnikov alcohol, alkenes can instead be treated with mercury...

Proteins are composed of amino acid units bound by peptide bonds. By the addition of the enzyme Bacterial Protease these bonds are broken and the individual amino acids are freed. A simple test for free amino acids is the use of the reagent Ninhydrin which turns purple in the presence of amino acids but remains yellowish in the presence of protein. I. Label one 250 ml beaker A and one 250 ml beaker B. To each beaker add l 00...

Just briefly explain number 2.
what happened chemically
Part 2. An acid is a compound that releases hydrogen ions (H+) when dissolved in water, creating an acidic solution. An alkaline or base is a compound that releases hydroxide ions (OF when dissolved in water, creating an alkaline or basic solution. Both hydrogen ions and hydroxide ions are present in water because water molecules dissociate and reform, and dissolved substances add or remove ions. pH is the measure of how much...

Determine the pH of the solution (to 2 decimal points) after the
addition of 11.7 mL of 6.14 M hydrochloric acid (HCl) to 624 mL of
0.735 M phenylamine (aniline)
(C6H5NH2).
Assume that the volumes are additive and that the 5% approximation
is valid.

2. It is the oxalate ion (C2O4 2- ), which is the conjugate base of oxalic acid, that will serve as the chelating agent for Fe3+ in our experiment. The goal is to determine the empirical formula of the coordination compound that will form. Let’s imagine some of the possibilities. a. A complex ion is comprised of a metal atom or ion at its center, to which is bonded molecules or ions (called ligands). What are the common coordination numbers...
