Essays on Molar Mass

Aims and Objectives of the Experiment

This experiment aims at studying the characteristics of titrations with the strength of different acids used in these titrations. This is done by drawing the titration curves of the different titrations that are carried out in this experiment and interpreting those curves. The units of measurement for this experiment are the standard units that are used in titrations. These are molarity (moles/liter) of substances while the quantities are measured in mL (milliliter).

Theory and Principles

Conductometry is a type of electroanalytical method in analytical chemistry. While other electroanalytical methods use equilibria or electrodes, conductometry is different and employs the conductance of materials ...

Research Question

The effect of increasing the concentration of two reactants, i.e. Calcium Chloride solution and Sodium Carbonate solution, on the percentage yield of Calcium Carbonate is to be studied in this experiment. The efficiency analysis for the production of Calcium Carbonate (also known as chalk) is to be carried out. The dependent variable in this experiment is the percentage yield of Calcium Carbonate, expressed as percentage (%). The independent variable is the concentration of the reactants, i.e. Calcium Chloride solution and Sodium Carbonate solution. The concentrations are expressed in moles/liter or moles/dm3. While the control variable is the mass of the ...

Introduction and Literature Review

The value for a drug is significantly impacted by the dissolution rate, chemical stability and solubility of the drugs thereby impacting the pharmaceuticals efficiency as well. In the pharmaceutical industry multi-component crystals such as hydrates, solvates, co-crystals and salts have a major role during the design of new solids. Solid does not self-crystallize. It crystallizes in varied forms depicting random crystal properties. Various approaches are used to modify solids like Salting, Solvation, Hydration, and Polymorphism. Apart from these approaches, Co-Crystallization is a promising new approach to modifying solids (Nauha, ...

Chemicals in action An acid and base reaction occurs when a complete exchange of electrons between the proton donor and proton acceptor occurs. In this process a salt if formed. In the definition, a salt is a substance formed from an acid by its replaceable hydrogen either wholly or partially by a metal or an equivalent radicle. Example of salt formation Mg+H2SO4→MgSO4+H2 Mg+HCl→MgCl2+H2 In the modern ionic theory, a salt is a compound of oppositely charged ions. From this point of view, there is no difference between NaCl and NaOH. Further, anhydrous aluminum chloride is not a ...

The main aim of the experiment is to prepare cyclohexanol by an acid catalyzed reaction of hydrocarbon compound like cyclohexene. Water is majorly used as a solvent in the experiment and with this, it is believed to be the highest in ratio when considering the nucleophile that attracts the carbon compounds. - For cyclohexeneC6H10, the mass = 8.5g; Molar mass is =82.143g/mol Moles of cyclohexene =mass of the cyclohexene measured (g)molar mass of the cyclohexene =8.582.143 =0.1035mol For H2SO4 used, the number of moles is given by; volume used=8.2mL Given that; 1L=1000mL Ɂ ...
