indicated by a very pale pink color. To calculate the molarity of NaOH‚ the following equation was used MNaOH x VNaOH = MKHP x VKHP therefore the molarity was .125 M. INTRODUCTION This lab experiment covers the preparation of standard solution and the acid/base titration. The first part of the lab is to prepare a standard solution of Potassium hydrogen per. A standard solution is a solution of known concentration‚ in which it is prepared using exacting techniques to make sure that the molarity

steps in the crystallization of an organic solid from a solvent and state the purpose of each operation. 1] dissolve solid product in minimum volume of hot solvent .. Purpose ... to get into solution 2] cool solution in a mixture of ice‚ water and salt. Purpose .. to enable pure product to crystallise‚ solubility decreases with temp‚ so cold. Impurities are present in small quantities‚ so do not saturate and are left in solution. 2a] if it all sets solid‚ you haven’t used enough solvent‚ so add a

sample of foul water using oil-water separation‚ sand filtration‚ and charcoal adsorption and filtration. Procedure: First‚ you have the measure the foul water sample and record it in your data table. You have to record what you see and smell before you filter anything out. Then you have the separate the oil from the water using the ring stand‚ rubber tubing‚ pinch clamp and funnel. After you have done that you record your results for after Oil-Water separation. Next‚ you have to put sand in a plastic

Due to rapid urbanization and uncontrolled growth rate of population‚ solid waste management has become acute in India. The current practices of the uncontrolled dumping of waste on the outskirts of countries have created a serious environmental and public health problem where as many issues. Plastic waste which is biggest problem in waste management is recycled in India in an “unorganized” way. 60% of the plastic-waste collected and segregated gets recycled back into materials for further processing

The moving phase is either a gas or a liquid and the stationary phase is usually a solid. The mixture to be separated is combined with the mobile phase. As the mobile phase "solution" flows over the stationary phase‚ the components of the mixture continuously equilibrate between the phases‚ based on their particular affinity for each phase. A higher attraction for the mobile phase leads to a higher concentration
