Calculate the moles of the magnesium chloride used in the back titration from your concordant results, from the equation of the titration below, the moles of Mg will be equivalent to the moles of excess EDTA.
3. Given the ratio of Ca2+ + Mg 2+: EDTA = 1: 1, calculate the…

The measure of the hardness of water is the combined concentration of calcium and magnesium ions. EDTA forms a large complex with magnesium and calcium ions. Eriochrome dye which is used as an indicator changes to pink in the

It was established that the ethanol concentration of the unknown was 13.805 ± 1.31% w/v.
High concentrations of ethanol (ranging between 0.3 and 0.4%) in the blood often lead to fatal consequences that include death.
The experiment has various application both in the laboratory and industrial applications. Drug manufacturing firms, for instance, use the procedure to test for the presence of anti-acid in drugs. The titration involves complex reactions where molecules or ions are formed when metals ions react with ligands or complexing agents which represent either one or more molecules.
The author states that the formula of Magnesium can be predicted with the use of atomic theory, which leads to the electron structure of Magnesium and Oxygen atoms. The aim of the experiment is to compare the empirical formula of Magnesium Oxide developed after the experiment with the formula developed during the experiment.
With respect to their structure, biochemists often refer to four different aspects:
Secondary structure, local interactions held together by hydrogen bonds between the lone pair of electrons of an oxygen atom and the hydrogen attached to a nitrogen atom.
Errors in experiments influence the expected results thus causes changes in values of the data obtained at the end of the study. Most errors especially in the laboratory set up, arise from mistakes in measurements. A laboratory consists of various equipment which, when used improperly result to errors.

Dysregulated cell cycle control is a primary mechanism of cancer (Deshpande, Sicinski & Hinds,
When employing qualitative analysis in determination of identity of unknown solution, similar tests are performed on a known and unknown sample and their characteristics are matched in order to determine
