special occasions like independence day. The excitement produced by fireworks like ‚ brightening the night sky and plunging it with vivid displays of colour and insignificant‚ which makes them a crowd pleaser. Behind all the excitement of fireworks‚ chemistry plays an important role in creating the vivid colours we witness lighting up the sky. The actual chemical reactions that take place in the explosions require the use of oxidisers‚ reducing agents and binders. The additions of varying metal chlorides

Solutions Solutions are a combination of solvents and solutes. When a solute dissolves into a solvent‚ the combined product of the two reactants is called a solution. The definition of a solute is the reactant that’s being dissolved. The only difference from a solute and a solvent is that the solvent is the one that’s doing the dissolving. Molecules randomly flow in all directions until there is an equal concentration throughout the solution. The dissolving process can vary depending

Detection of Ions in Solutions Using Acid/Base Chemistry: A Quality Control Test Objective: This lab focuses on the detection of ions using titration as an analysis tool. You will standardize NaOH and HCl solutions so that you know the exact concentration and then prepare samples of common household items in order to determine the amount of calcium in Tang®‚ Mg(OH)2 in Milk of Magnesia‚ etc. You will learn to prepare samples of a specified concentration‚ learn about acids and bases through

Chemistry and Society According to the Merriam-Webster Dictionary‚ accuracy is “freedom from mistake or error: the quality or state of being accurate: the ability to work or perform without making mistakes” ("accuracy‚" 2014). Precision‚ however‚ is “the quality of being precise” ("precision‚" 2014). That doesn’t really help with the definition much. After subsequently checking the definition for precise it means to be “very careful and exact about the details of something” ("precise‚" 2014). The
