Taking a Look at Maalox

The experiment is to observe a variety of chemical reactions and to identify patterns in

The purpose of this experiment is to examine the stoichiometric relationship between reagents and the identity of the products by using three acid/base neutralization reactions of a triprotic acid, phosphoric acid, and varying molar equivalents of sodium hydroxide. The data will be used to determine the formula weight of the products and identify the remaining salt for all three reactions.

The purpose of this lab was to determine the limiting reactant in a mixture of to soluble salts and the percent composition of each substance in a salt mixture.

Procedure: In this experiment, various chemicals were mixed together, to determine a reaction. Using two drops from chemical 1 and two drops of chemical two, unless otherwise stated, then recording the type of physical reaction or color changes that occurred.

When the tip of the rod touched the pH paper, the color of the pH paper became blue.

A chemical reaction is when substances (reactants) change into other substances (products). The five general types of chemical reactions are synthesis (also known as direct combination), decomposition, single replacement (also known as single displacement), double replacement (also known as double displacement), and combustion. In this lab, the five general types of chemical reactions were conducted and observations were taken before, during, and after the reaction. Then the reactants and observations were used to determine the products to form a balanced chemical equation. The purpose of this lab was to learn and answer the question: How can observations be used to determine the identity of substances produced in a chemical reaction?

Conclusion – The main idea of this experiment is that if you have the reactants of a double replacement reaction that you should be able to find out several things. First, you can figure out the products from switching the positive ion with the other positive ion. Once you have found the products you can determine the phase of matter they are in from Table F and H. Finally, you can also determine whether the reaction went to completion or not. The observations and data above leads me to believe that our experiment is valid. We were very careful and observant of the directions that needed to be taken. Once source of error could have been that certain substances were placed in the wrong wells, causing your data to stray from the correct information. One way this experiment could be applied to a real life situation is he residue in the bottom of a glass in your bathroom. There is stuff dissolved in water, and any trace of water left in a glass will eventually evaporate and leave the residue.

In this experiment you will observe some physical and some chemical changes. You will observe that energy must be used to start some chemical reactions, and that it is produced in others.

The objective of this experiment will be to combine various substances, liquids and metals, and to observe their behavior when they are combined. The types of reactions observed shall determine the nature of these reactions: physical or chemical.

Purpose: The purpose of this experiment is to observe a variety of chemical reactions and to identify patterns in the conversion of reactants into products.

The purpose of this experiment is to distinguish the relationships between reactants and products, in addition to expanding on concepts such as single displacement reactions, mole ratio values, moles to mass, theoretical yields, limiting reactants, excess, stoichiometric relationships and percentage errors.

The purpose of this lab is to decipher and observe the four types of reactions.

The instructions I was given directed us to perform perform a lab where I performed a reaction the reaction between an active metal and an acid. The purpose of this lab was so we could observe said reaction and hopefully gain a better understanding of what we are currently leaning in class. I hypothesis, if we add dilute hydrochloric acid with magnesium, then there will be a reaction that produces heat because of the rapid exchange of electrons between the two. The materials used within the lab are, an apron, goggles, a clamp and stand, a thermometer, a pipette, hydrochloric acid, and magnesium.

As the acid was being added, the mixture was being stirred over a stir plate. Once completed, the reaction mixture was poured from the round bottom flask into a 500 mL separatory funnel and its top (organic) layer was extracted into another beaker. The bottom (aqueous) layer was placed back into the funnel and extracted twice with 50.0 mL of ethyl ether each. The newly extracted layers were combined and dried over magnesium sulfate (MgSO4). The dried solution was the decanted into a beaker to remove the MgSO4 salts and the product solution was collected via Buchner vacuum filtration. The resulting product was transferred into an Erlenmeyer flask with an inverted beaker on top and stored in a drawer.

Maalox is an antacid - a drug comprised of aluminum hydroxide, magnesium hydroxide, and simethicone; it is designed to neutralize stomach acid (Lilley, Collins, & Snyder, 2017). Lowering the level of acidity in the stomach usually provides pain relief for patients suffering from gastritis and/or gastric ulcers. The patient needs to be informed that the presence of antacids in the stomach reduces the efficacy of tetracycycline. This might be the reason why his condition is not improving. The patient needs to be advised that for peptic ulcer antacids should be taken atleast 2 hours apart from other medication usually 1 and 3 hours after meals and at bedtime for 4-6 weeks (Saunders, 2017).
