Texas State University- San Marcos in room 117 of the chemistry building. The concentrations used in the experiment were both .5 M sodium hypochlorite and sodium thiosulfate. The concentrations of the solutions found in the dumpster were calculated to be .806 M (both sodium hypochlorite and sodium thiosulfate as well). This was found by taking the 6.0% (by mass) sodium hypochlorite and multiplying it by 1 gram of solution‚ 1000 mL and 1 mol NaClO. This result was then divided by the result of 100g

was able to pass all of them. I recommend using sodium carbonate as your substance. Of all the substances‚ only two were covalent and two were ionic. The ionic substances‚ sodium chloride‚ sodium carbonate‚ and salicylic acid‚ came close to the description you requested. The covalent substances‚ sucrose and salicylic acid‚ did not match the descriptions. The best substance would definitely be sodium carbonate‚ since it passed all the tests. Sodium carbonate had a high melting point‚ so it will be

While the excess iodine is the titrated by standardized sodium thisulphate(Na2S2O3) as shown the equation below. Then‚ the iodine reacted with ascorbic acid can be determined followed by the content of ascorbic acid. third Starch indicator is added for the determination of the end point of the titration

All the homeowner ahs to do while using drain cleaner is to pour I down the clogged drain and maybe run some water‚ inside the pipe the chemicals go to work for you. But even though it sounds simple precaution must be taken in order to prevent injury to our body. NaOH must be produced correctly before it can be used in drain cleaner‚ a very caustic substance. The main ingredient in most drain cleaners is the very strong base‚ sodium hydroxide (NaOH

Introduction: Thermochemistry is the branch of chemistry that studies the energy and heat associated with chemical reactions and/or physical transformations. A reaction may release or absorb energy‚ and a phase may change‚ such as in melting and boiling. Thermochemistry focuses on these energy changes‚ particularly on the system ’s energy exchange with its surroundings. In combination with entropy determinations‚ it is used to predict whether a reaction is spontaneous or non-spontaneous‚ favourable

This is then reduced by means of iron powder or sodium sulphide to get para-aminophenol. The recovery of para-aminophenol is completed by dissolving the para-aminonphenol hydrochloride salt in water‚ decolourising the aqua solution and crystallising the para-aminophenol by neutralizing the salt.

University of Santo Tomas España‚ Manila Abstract Soda ash is the common name for sodium carbonate (NaCO3)‚ a chemical salt derived from carbonic acid. It is frequently used in manufacturing‚ industry‚ and in domestic chores. Glass production is one of the primary industrial uses for sodium carbonate. It is also used as an additive for detergents‚ and it can also be used in cooking as a food additive. Sodium carbonate is a natural water softener‚ as it prevents hard water from obstructing the

value can be defined by several factors. For the purpose of this paper‚ I compared calories‚ protein‚ carbohydrates‚ sugars‚ fats‚ sodium‚ and cholesterol. The way I determined which would be the healthier or more nutritious option was comparing these categories between the two. The higher an item is in calories‚ the lower the health value. The same is true for sodium‚ fats‚ sugars‚ cholesterol‚ and carbohydrates. Protein is a good presence here. After comparing the two items‚ I tallied which one
