Road salt‚ also called rock salt‚ is sodium chloride‚ chemically combined with NaCl. Na is the chemical abbreviation for sodium and Cl is the abbreviation for chloride. Table salt that we use is exactly the same chemical. The US Environmental Protection Agency has set limits on allowable levels of chloride in water but not sodium. In high concentrations both sodium and chloride can be harmful to aquatic organisms. Sodium is the primary concern for humans‚ as it can be harmful to people with high

Is salt really that bad? Sodium is an essential electrolyte found in salt. Sodium is a mineral that carries out vital functions for the body some of which include maintaining fluid balance‚ regulating blood volumes‚ nerve transmissions and hydration. Sodium is important in ensuring healthy heart functions and muscle contractions. Some individuals have a higher need for sodium as it can be depleted through exercise (via sweat). If sodium levels are lower than recommended it needs to be replaced

EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol

Experiment 2: IDENTIFICATION OF UNKNOWNS BY TLC AND MP IN COMBINATION Introduction: Thin layer chromatography (TLC) is one of the most valuable techniques in organic chemistry. This is a best method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different

SALTS EVERYDAY First some words about salts in chemistry. Salts are ionic compounds that can result from the neutralization reaction of an acid and a base. They are composed of related numbers of cations (positively charged ions) and anions (negative ions) so that the product is electrically neutral (without a net charge). Salts can appear to be clear and transparent (sodium chloride)‚ opaque‚ and even metallic and lustrous (iron disulfide). In many cases the apparent opacity or transparency are
