Cations I found out what Cations where present by doing a flame test. When I put my substance in the Bunsen burner I got a bright yellow colour which means that the Cation for my substance was sodium ions. Anions To find the Anions I had to go through a series of tests to find out which Anion was present. From all the tests I found out that the test for bromine halide worked and the test for sulphate also worked. Conclusion In conclusion I found out that the ions present in my sample where

Introduction Tensile test is also known as tension test. It is material’s strength test where pulling force is applied from two ends. It is very important mechanical property evaluation test which provides fundamental properties like strength‚ stiffness‚ elastic limit‚ ultimate tensile strength etc. in this test‚ test object are standard size and shape but different material‚ then direct comparison of properties of those materials can be made. We had used standard “dumb-bell” shaped
