Question: what is the appropriate method of identifying compounds as either ionic or covalent based?

Background/Hypothesis Ionic compounds are created from the strong electrostatic bonding between ions (Brinker, and George 393). The covalent compounds have are formed by bonds that result from sharing of electrons (Mah 31).

Solubility test Conductivity test Melting point test Color and odor test Oxidation with oxygen test Steps/Procedures. Solubility test 0.25 grams of the chemical was placed in a test tube. 1 mL of water was added and stirred using a stirring rod. The addition of I mL was added until the chemical dissolved. The chemical that did not dissolve after adding 10 mL of water was recorded. The ...

Introduction

H2S or hydrogen sulfide is a gas that naturally occurs in hot springs, crude petroleum, and even natural gas. Hydrogen sulfide is also known as sewer gas, swamp gas, manure gas, or stink damp. This gas is usually produced by the breakdown of organic materials commonly found in wastes of human and animals by bacteria. Some of the activities that commonly result to the production of hydrogen sulfide gas include treatment of wastewater, drilling and even refining of petroleum or natural gas, and kraft paper mills (Occupational Safety and Health Administration). Aside from being a gas in form, hydrogen ...

Introduction

Many countries across the world are faced with the problem of water and soil contamination. The contaminations are caused by industrial effluents, military actions and agricultural activities among others. Human carelessness and ignorance also contribute significantly to water contamination. As a result, new biological, chemical and natural activities have been invented in order to control water contamination. One of the most successful measures used in control of water contamination is phytoremediation. It involves the use of plants to absorb pollutants from contaminated water found on the surface of the land and in the soil. This paper discusses the biological ...

Introduction

Quality is the characteristic of a service or a good to be fit for use by the customer or the consumer. The pharmaceutical quality means the production of a product that is free of contamination that gives the therapeutic benefit that is labeled in the container to the customer. This quality is either evaluated in vitro or vivo by the tests performed. In quality design, the vitro product is ensured to have good performance and the same provide a similar quality in the vivo performance test. In this case, the product performance is related to the product performance.

Quality by Design (QbD)
