Concentration and Dilution

Hello readers today I'm going to be making a new blog post about Chemistry. Today in chemistry we are learning about Concentration and Dilution. Concentration, A measure of how much solute has been dissolved in the solvent. In other words - how much solute there is in the solution. How dilute something is ( how weak) How concentrated something is ( how strong it is). What is dilution? Making something less concentrated There will be less particle in the liquid. Our experiment is a dulution series. Equipments: a potassium pomegranate crystal, six large test tubes, tweezers, a plastic franser pipette, a test tube rack, 10 ml measuring cylinder. 1. place the sict test tubes in a test tube racl. Label the rack with numbers 1 to 6.  2. Using the measuring cylinder, fill test tube 1 with 1- ml of water. Fill the remaining test tubes with 5 ml of water. 3.Using your tweezers, add a single crystal of potassium pomegranate to test tube 1. 4. Gently shake the test tube until the crystal has dissolvede. 5. Using the transfer pipette, carefully remove excactly 5 ml from test tube 1 and pour it into test tube 2. 6. rinse the transfer pipette throughly to ensure that no purple solution remains. 7. Gently shake test tube 2 and repeat the transfer process, transferring excatly 5 ml of solution from test tube 2 to test tube 3. 8. Rinse the pipette again and re[ear the transfer process fo0r test fubes 4,5 amd 6. The color got lesser or more dilute We used potassiumm  permanganate. permanganate is the general name for a chemical compound containing the manganate(VII) ion, (MnO  4. ). Because manganese is in the +7 oxidation state, the permanganate(VII) ion is a strong oxidizing agent. The ion has tetrahedral geometry.
