analyze data and draw a conclusion. In this experiment I will find out that in a type of water the Alka-Seltzer will dissolve faster and slower. Alka-Seltzer is one of the world’s best known antacids. Its main function is to absorb excess stomach acid. II. MATERIALS: * Tap Water - Warm Water * Cold Water - Salt Water * Acidic Water -5 cups (250 mL of water in each cup) * A whole Alka-Seltzer tablet III. HYPOTHESIS: My hypothesis is that the Alka-Seltzer tablet

Acid-Base Extraction: Separation of an Organic Acid‚ Base and a Neural Compound Introduction/Background Acid base extraction is a widely used commercial method in separating acids‚ bases and neutral compounds. This is concept is based on several physical properties of the compounds‚ such as boiling point‚ melting points and solubility. The different solubility properties of the protonated and non-protonated forms of these compounds depend on the functional groups present‚ such

Excretion. a) excretion is the removal or metabolic waste from the body. Metabolic waste consists of waste substances that may be toxic or are produced n excess by reactions inside cells. b) Explain the importance of removing metabolic wastes‚ including carbon dioxide and nitrogenous waste‚ from the body. The are many substances that need to be excreted - almost any cell product that is formed in excess by the chemical process occurring in the cells must be excreted. However there are two

Experiment Acids‚ Bases‚ and Neutrals Problem Are common house-hold products pH balanced and neutral? Information Gathered pH measures how acidic or alkaline a solution is. The pH scale ranges from 0-14. Solutions that range from 0-6 are considered to be acidic. Solutions that are on the acidic end of the scale are low in pH‚ high in hydrogen ion‚ and low in hydroxyl ions. An acid has a sour taste‚ hence‚ will react to metal and will be corrosive; therefore‚ they are considered as an electrolyte

Percent Acetic Acid in Vinegar Introduction: Acetic acid is reactive when combined with calcium carbonate. In this lab‚ we will use vinegar for its acetic acid and egg shells for their calcium carbonate. Marketable vinegar differs in its acetic acid concentration from 4-6%. Calcium carbonate reacts with the acetic acid in vinegar to produce carbon dioxide‚ water‚ and calcium acetate as represented by the equation: CaCO3 + 2HC2H3O2 CO2 + H2O + Ca(C2H3O2)2. The calcium carbonate reacts with

Ethanoic Acid Advantages: Ethanoic acid is non-toxic and is a weak acid‚ meaning it will not do any damage to most surfaces as it does not corrode or bind to other metals‚ therefore can be easily removed through washing or rinsing it. Disadvantages: Ethanoic Acid is the slowest de-scaler of the three acids‚ and is therefore the least effective. It also may cause an unpleasant smell‚ and can have a negative effect on the taste of coffee meaning one would need to spend longer time rinsing and cleaning

Experiment 3: Stoichiometry of a Precipitation Reaction Abstract: In this experiment‚ the objective is to use Stoichiometry to predict the amount of product produced in a precipitation reaction. We received working knowledge of how to accurately measure reactants and products of the reaction. We then are able to use the data that we recorded to make assessments of the actual yield opposed to the theoretical yield. When we calculated the percent yield we are able
