2KMnO4+5Na2C2O2+8H2SO4→2MnSO+K2SO4+5Na2SO4+10CO2+8H2O KMnO4 solution is unstable in air because it is oxidized to MnO2 spontaneously by a reducing substance in distilled water. Standardization will be interfered by this brown colour MnO2 especially in the presence of light. So MnO2 has to be removed by filtering the solution since it is insoluble in water. In that hot Na2C2O4 decomposes into CO2 and H2O in the air by the presence of acid: C2O42-+O2+2H3O+→H2O2+2C2O+2H2O The titration is started at room temperature

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

Explain how human activity can affect water availability and quality. (10) Agriculture plays a significant role in the quality of water and three factors come into play when considering agricultural effects: pesticides‚ fertilizers and the waste produced by farm animals. When pesticides or fertilizers are applied to crops the excess materials will either run off the land‚ or seep into the groundwater‚ with an eventual ending in bodies of water such as lakes‚ ponds‚ or streams. The excess nutrients
