Here are some key themes to explore with the audience once the activity is complete. Adjust the details to match the level of your audience. The formation of tin crystals from the tin(II) chloride ...
Silicate is analyzed using the technique of Armstrong et al. [Arms67]. Acidified ammonium molybdate is added to a seawater sample to produce silicomolybdic acid which is then reduced to ...
The idea of making your own semiconductors from scratch would be more attractive if it weren’t for the expensive equipment and noxious chemicals required for silicon fabrication. But simple ...
The standard go-to solution is ferric chloride. It isn’t too tricky to use, but it does work better hot and with aeration, although neither are absolutely necessary. However, it does tend to ...
Sodium Chloride is an alkali halide with an fcc crystal structure. The basis is two ions, a sodium cation and a chlorine anion. The crystal lattice parameter is 0.563 nm. The diagram shows both a unit ...
Most people are familiar with sodium chloride (commonly known as salt) as a kitchen ingredient, but it also has important medical uses. Sodium chloride (NaCl), also known as salt, is an essential ...
A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic compound sodium chloride is formed. A sodium and chlorine atom are near ...
Sodium chloride, calcium chloride, lithium chloride, potassium chloride, copper(II) sulfate (1 g per salt per group) Concentrated hydrochloric acid (teacher to control and dispense small ...
Gum Health: Toothpastes formulated for gum health often contain stannous fluoride or triclosan to fight gingivitis. Tartar ...
Here’s an example using sodium and chlorine. They form ions which bond to form sodium chloride. 2. Work out how many electrons need to be transferred. 3. Draw the electronic configuration of the ...
