We found that the convection current for distilled water was slightly different from the current of acid rain. On the basis of our observations, the convection current for rain water moved slightly more quickly. This was evident when the tank containing the acid rain was put onto the hot plate, and it could be seen that its convection current was faster than distilled water's. This is because it takes less time than the distilled water for the particles in acid…...

The aim of this investigation is to find out what antacid tablet works the best. We will be finding out which antacid tablet is cost efficient and which antacid tablet if effective by this I mean the one that can hold acid the most This can be done by using a pH probe, and seeing how long it takes to make the antacid tablet turn the HCl back to an acid. The best antacid tablet will be cost effective, so…...

Use of concrete dates back to 3000BC and was only used for industrial purposes. But as time passes it has become one of the most standard materials used and even plays a major role in the infrastructure sector. This fact itself makes it a potential subject for researchers who are in line to concrete production and development. However present-day research shows that some of the current concrete treatment methods, such as the application of chemicals and polymers in the production…...

Titration Of Acids And Bases
Words • 1001
Pages • 5
Introduction According to Arrhenius definition, acid is substance that produces H3O+ ion while base is substance that produces OH- ions. The reaction between acid and base often yields the products of salt and water. The formation of water in this neutralization reaction is caused by the combination of H3O+ and OH- ions. In order to determine the concentration of an unknown acid and base, a method called acid-base titration is used. The end of the titration has been reached when…...

Determination of CaCO3 in toothpaste
Words • 1588
Pages • 7
SYNOPSIS The purpose of this experiment is to use the back titration method to determine the percentage of calcium carbonate in toothpaste. Instead of using standard titration methods where an acid is titrated directly using a standard solution of a base, back titration is used because the sample to be analysed, CaCO3 does not dissolve in water. Hydrochloric acid and sodium hydroxide are the reagents used in this experiment. The precise measured amount of HCl is added to the weighted…...

Synopsis: The main aim of the experiment is to find out the amount of calcium carbonate in toothpaste through back titration since calcium carbonate does not dissolve in water. A roughly weighed amount of calcium carbonate is mixed with hydrochloric acid and then titrated against sodium hydroxide. When the indicator turns from pink to orange, the volume of sodium hydroxide used is taken down. After doing some calculations, the average percentage of calcium carbonate in toothpaste is 19.2%. This average…...

The purpose of this experiment is to examine the percent yield of a precipitate in a double displacement reaction. A solution of calcium citrate and sodium carbonate were mixed together, then the products were filtered out as so only the precipitate remained. The filtered paper was then dried and the mass of the precipitate in the experiment divided by the theoretical mass of the precipitate from the calculated gave the percent yield. The percent yield that was acquired is about…...

Abstract Identifying this organic acid was an extensive task that involved several different experiments. Firstly, the melting point had to be determined. Since melting point can be determined to an almost exact degree, finding a close melting point of the specific unknown can accurately point to the identification of the acid. In this case the best melting point range was 207-209 degrees Celsius. Melting point, while very helpful in identifying an unknown organic acid, is simply not enough. Next, a…...

A large variety of analytical techniques and procedures, ranging from instrumental methods such as spectroscopy and chromatography to more classical processes, such as qualitative and gravimetric analyses, have been used to help chemists identify unknown compounds. Gravimetric analysis is a type of quantitative analysis, concerned with determining how much of one or more constituents is present in a particular sample of material. Gravimetric analysis derives its name from the fact that the constituent being determined can be isolated in some…...

Abstract: In this experiment Stoichiometry of a Precipitation Reaction, the main objectives were to use stoichiometry to calculate the theoretical yield of CaCO3 that precipitates from the reaction between Calcium chloride, Dihydrate and Sodium carbonate, and then compare that value to the actual yield. In order to do this accurately, we must be able to measure the products and reactants with accuracy. The last objective of this experiment is to calculate the percent yield of the product produced.
