This article from the United States Environmental Protection Agency (EPA) explains what conductivity is, and how to measure conductivity. This is perfect for the experiment because it combines knowledge of how to measure the conductivity of substances along with what is, which is what is being tested. According to the EPA, “Conductivity is a measure of the ability of water to pass an electrical current.” This makes sense as to why in the experiment, distilled must be poured on the powders. The source continues to explain that the conductivity of a substance is affected by inorganic solids being dissolved into water. Inorganic solids inside of water have a very low conductivity, so if a powder is tested and it has a very low conductivity, it

This episode of Mythbusters shows how the different Alkali metals react with water. They explain how as you move down the group, the more unstable the elements are, making each one more reactive and sometimes explosive than the last. The hosts do experiments with Rubidium (Rb) and Caesium (Cs) and show its reaction in a toilet. They can not test Francium (Fr) because it is radioactive and do not have the legal authority to use the explosive element. In the experiments, the different reactions are present between Rubidium and Caesium. Rubium has a less explosive and and smokey reaction as Caesium does.
This source is a reliable source because the creators of the show have worked special effects for over 20 years, and have worked to bust or prove myths like Alkali metals being explosive like grenades. They strive for the truth and end up with the truth. They challenge what people say to be true and provide evidence to show it to be either correct or fake. They are allowed to work in official bomb testing sites according to what they say in their show and they have the Fire Department there in case anything were to go wrong. They know science, and work to show the truth. The Alkali metals will not change from 2008 to 2015, they have not changed and will not …show more content…
Thus, the letters pH stand for “power of hydrogen”. More simply put, pH is the measure of acidity or basicity of the solution. pH is the level of acidity on a scale of 0 to 14 in which 0 is the most acidic while 14 is the most basic. To put it in perspective, the pH value of pure water is 7, the pH value of hydrochloric acid is 0, and sodium hydroxide is around 14. The range of 0 to 14 uses the practical limits that pH puts on some solutions. This means that some solutions are able to exceed this scale and reach pH levels of -1 and 15, but these pH’s are not simple to concoct and their creation is not very
