Experiment #7: Acids‚ Bases and Salts Mabag‚ Viannery D.‚ Mangune‚ Paolo D. Chem 14.1‚ MAB1‚ Ms. Angelyn del Rosario March 8‚ 2010 I. Abstract The experiment allowed students to explore different electrolytes and classify them into acids‚ bases and salts by using different indicators or by measuring the pH levels of each. The experiment also helped students classify different substances through their conductivity properties. The preparation of a 1 M stock solution from NaOH pellets diluted to a

The purpose of this experiment is to separate a solution of an acidic and organic compound and purify its respective acidic product through the techniques of an acid base extraction‚ recrystallization‚ and use of Melt Temp (melting point range). The reaction of an unknown acid (3-chlorobenzoic acid) with diethyl and sodium hydroxide was observed‚ and the solution naturally separated into an aqueous and organic solution. The mixture of acid and organic solution was created and then separated through

Extraction of R’-NH2 For both of the organic acid and organic base extraction‚ the addition of the respective inorganic acid or inorganic base (HCl or NaOH) to the three-component mixture caused an immiscible appearance of the solution in the separatory funnel. By briskly shaking the separatory funnel with the mixed components created a build up of pressure which was released through the stopcock forming small disappearing bubbles within the tip of the separatory funnel. Once the funnel was placed

Five major theoretical bases for counseling in psychology are biological‚ learning‚ cognitive‚ psychodynamic‚ and sociocultural. Each one of these perspectives searches for answers about behavior through different techniques and researching a clients childhood or adult life experiences looking for answers to different kinds of questions. Due to the different types and styles of counseling approaches‚ each counselor forms their own thoughts and explanations. The premise behind the biological perspective

MONEY AND CREDIT Double coincidence of wants is an essential feature When both parties have to agree to sell and buy each others commodities. This is known as double coincidence of wants. What a person desires to sell is exactly what the other wishes to buy. A barter system has deficiencies. 1.
