Sodium hypochlorite

traces of salt (sodium ethanoate and sodium sulfate) and remaining soluble impurities when it is discarded (AUS-e-TUTE. 2015.) Any remaining traces of ethanoic acid and sulfuric acid is neutralised by sodium carbonate (as shown in equation 1) (Fischer esterification reaction), which is converted to soluble sodium sulfate, sodium ethanoate and carbon dioxide which is released by inverting the separating funnel, and opening the tap. Equation 1: Ethanoic Acid + Sodium Carbonate  Sodium Ethanoate…

to dissolve the scale, and weak enough to not damage the pipe itself (Oxlade 32). Another weak acid is vinegar. Before refrigerators were invented, food was kept in vinegar, because the acid would kill the microorganisms that feed on the food (33). Sodium hydroxide, a strong base, is used in oven cleaners because it is very corrosive. It reacts with grease in the oven so that it can be washed away with water. Many soaps and detergents are bases, too (32).Neutralization reactions can also be…

substances. The following sets of substances could have been assigned: Set 1 - Silver nitrate (AgNO3), Manganese(II) nitrate (Mn(NO3)2), Barium nitrate (Ba(NO3)2), Hydrochloric acid (HCl), Sodium Hydroxide (NaOH); Set 3 - Silver nitrate (AgNO3), Barium nitrate (Ba(NO3)2), Hydrochloric acid (HCl), Sulfuric acid (H2SO4), Sodium Hydroxide (NaOH); Set 4 - Silver nitrate (AgNO3), Lead (II) nitrate (Pb(NO3)2), Hydrochloric acid (HCl), Ammonia (NH3), Water (H2O). From the substances above Hydrochloric…

This scientific experiment will entail the rate at which ice will melt with different types of salts that include, table salt, sea salt, and rock salt. Salt melts ice essentially because adding salt lowers the freezing point of water. Although we know that salt has the ability to melt ice, we are testing whether sea salt, table salt, or rock salt melts ice more efficiently by calculating the amount of time it takes to melt the ice. We will begin by placing the same quantity of each type of…

Purpose Statement: The main ingredient in my favorite seasoning, Adobo, led me to choose salt as my topic. After doing background research, I learned there were three ways of making salt and the one I found most interesting was solar salt. My decision to focus this paper on solar salt was also influenced by the fact that I never bothered to know how salt was created or obtained, and I like learning about environmentally friendly products. My intended audience is the class and the professor. I…

Alkalinity is a measure of the ability of a water to resist changes in pH. Alkalinity in water is due to the presence of weak acid systems that consume by hydrogen ion produced by other reactions, allowing chemical or biological activities to take place within a water without changing the pH (1). In this way the alkalinity protects aquatic life. The measured value may vary considerably with the end-point pH used. Alkalinity is a measure of an aggregate property of water and can be interpreted…

looked at for its physical characteristics. WD has light, tan color and a soft texture, resembling the wood of a pine tree. The density of it was also calculated and had a 20% error. Through the acetic acid test, PE mirrored the characteristics of sodium bicarbonate. They both create a large chemical reaction in which fizzing and bubbling occur. The Australians will get LF, MA, and WD through a density comparison, and PE through an acetic acid…

acid base reactions. The reaction used in this lab is: C_20 H_14 O_(4 (aq))+46 NaOH_((aq))→46 Na_( (aq))^++20 H_2 CO_(2 (aq))+10 H_2 O_((l)). Phenolphthalein and sodium hydroxide react to form carbonous acid, water, and Na+ ions. This reaction is a neutralization reaction, where phenolphthalein, a weak acid, reacts with a strong base, sodium hydroxide. When phenolphthalein is put into a basic solution, it turns pink. The phenolphthalein ion is pink, and when a base and phenolphthalein are…

Every year during winter months, icy surfaces create a dangerous problem for drivers and pedestrians. Icy roads and sidewalks can become very hazardous for travel. A solution must be implemented to mitigate risks associated with winter travel. This problem is relevant to the experiment since I will be testing different methods of melting ice. The solution resulting from the experiment can be used throughout the world to make our roads safer. The literary reviews for this experiment are from…

Racheal A. Krasner Professor Garfield Beckford CHEM 1211 L 25 September 2015 Lab Report Concerning Acid-Base Titrations The purpose of this experiment was to recognize the procedures for conducting acid-base titrations. Each acid-base titration used one solution to analyze another; it also involved the use of an indicator, which denoted the endpoint of the titration. The indicator used was phenolphthalein; it produced a pink hue when the titrations reached their endpoints – between pH 8 and pH…
