If you've ever attempted to churn out homemade dishwasher detergent and have ended up disappointed with the outcome, the possibility is that you were very close to creating a superb recipe than you had expected of. Majority of the DIY formulas are done with the very same components, however, there lies a trick that you can leverage to make it work. The thing is, cleaners like washing soda are taken under consideration as a base, while the accumulation removers such as citric acid happen to be..

How does changing the concentration of Hydrochloric acid affect its rate of reaction with Sodium Thiosulphate? Introduction/aim - the aim of this experiment is to see how changing the concentration of hydrochloric acid would change its rate of reaction with Sodium Thiosulphate. This was done by changing the concentration of Hydrochloric acid to 4 different concentrations and adding them to the same amount of sodium thiosulphate. This is done in different beakers that will previously be placed over

Evidence suggests that mining has gone on since the beginning of the human race. One of the oldest discovered mines is thought to be 43,000 years old, known as the “Lion Cave” in Swaziland. Archeologists believe that these ‘miners’ were mining for hematite so that they could make ochre pigment, a type of paint used back then. The Swaziland Iron Ore Development Company discovered that there had been about 100,000 tons of material removed from the Lion Cave, most likely by these prehistoric miners

Calcium was discovered by Sir Humphry Davy at England in 1808. Calcium is a soft, gray metal. When it burns, it burns with a yellowish-red flame. When it is exposed to air, it develops a gray-white coating because it reacts with the oxygen in the air to form a coating of calcium oxide .Calcium comes from the Latin word calx meaning lime. Compounds such as lime were prepared by the Romans in the first century under the name calx. Literature dating back to about 975 AD notes that plaster of Paris is

An egg has the capability of withstanding a large amount of force as long as the force in distributed evenly around the egg. For example, an egg can be thrown like a baseball and sometimes the egg won't break if it lands from a high toss into grass. When the force of an egg is focused at one point it will break but if it is evened out around the egg, the egg has a higher chance of not breaking. Along with evening out the force, it will also benefit the egg if the impact is decreased with the help

The idea of having perfectly white teeth has been an issue almost everyone has encountered before. There have always been different remedies for getting your teeth the whitest with one of the newest inventions being whitening strips. There are four main parts of the tooth: there is the enamel that “makes up the protective outer surface of the crown of the tooth.” (Overman, Vickie) The crown is a tooth shaped cap that is over the tooth. Then there is the dentin and that “makes up the majority of

180 ppm is considered very hard.2 It is important to study the hardness of water because of the of the problems that can arise when left untreated. Hard water can cause a build-up in plumbing fixtures or water heaters. This happens when calcium carbonate is deposited as calcite crystals on the inner surface of pipes, and evaporator surfaces. The build-up can cause a blockage in pipes, and eventually corrode the metal of the pipes.3 Water hardness can be determined

The purpose of this investigation was to determine the relationship between pH and water hardness. Water samples from above the Mount Morgan mine site and below the Mount Morgan mine site were also compared. 8.1 Analysis of the Data It was hypothesised that the water sample from above the mine site would be of better water quality than the sample from below the mine site. It was found that this was, in fact, the case. As seen in Table 7.2, the above sample had lower acidity, hardness and conductivity
