The Solubility of Potassium Nitrate Aim: The aim of this experiment is to find out by how much the solubility of potassium nitrate into distilled water increases when the solution is heated‚ and if yes‚ by how much. Hypothesis: According to data on the internet‚ 3.75 × 10¹ moles of potassium nitrate dissolve in 100g of water. I believe this information may be correct. I also believe that as the solute is absorbing outside heat‚ the energy is increased causing it to dissolve both faster‚ with

The positive Silver ions in the Silver nitrate ions react with the chlorine in in this net ionic reaction: Ag+(aq) + Cl-(aq) = AgCl(aq) Silver Chloride is an extremely insoluble compound‚ as it has a Ksp constant of 1.6 * 10-10 which means the reverse reaction of the Silver Chloride dissolving

The hypothesis If a chemical reaction occurs‚ then there will be indicators of a chemical change‚ was supported throughout this experiment. Throughout this experiment there were several reactions that took place‚ and an indicator of such chemical reactions could be seen throughout each one. The first piece of identifiable evidence was present in the first step‚ which was when copper (II) nitrate and sodium hydroxide were combined. When stirred‚ a blue precipitate formed at the bottom of the test

Many people know all about “standardized tests”. This was an issue for me‚ at first I was not very alluring to the idea of standardized tests‚ I felt that standardized test were a tedious subject‚ something that no one really wanted to listen or learn about; since many already know about standardized test. But I was wrong. Throughout the weeks‚ I learned that not many people actually know about the issues dealing with standardized tests and how it affects a myriad of people. Standardized tests are
