Green Chris Christopher is in his last year of his degree in Agrobiology. He needs to complete a 6 months internship with the Agri-food and Veterinary Authority AVA of Singapore. He has prior experience in growing crops of tomato and achieving at least a 95% yield. In the lab‚ his supervisor Dr Ong decided to challenge him. Dr Ong said: “Hi Christopher‚ welcome to our AVA laboratory. We are pleased to have you here. We have some problems growing Rhododendron.” Christopher replied: “Thank you

A Titration is a process of the concentration of one solution being determined by its reaction with either a standard solution or a known quantity of solid dissolved in solution. It may also be used to calculate the molar mass of an unknown acid or base. Purpose: I. Prepare a standard solution of sodium hydroxide II. Standardize a sodium hydroxide solution by using potassium hydrogen phthalate (KHP) III. When given whether the acid is monoprotic‚ diprotic‚ or triprotic ‚ determine the

MEASURING pH Date of Lab: 02/09/13 Date Report submitted: 02/26/13 Purpose of the experiment By doing this experiment‚ we were trying to learn how to measure a pH with a pH meter to determine whether a solution is weakly‚ moderately or strongly acidic or basic; but also to compare the different data founded to see how the addition of certain liquid to a solution may affect the pH of the initial solution. Materials We used: * Tap water‚ distilled water‚ Soda and milk as the main

procedure is to weigh out your acid‚ dissolve it in water‚ add a couple drops of the indicator (phenolphthalein)‚ and then add the sodium hydroxide until you note a color change (from clear to pink). When the color change occurs‚ you have added enough base to completely react with the acid (the endpoint). You are allowed three trials‚ and will be graded on accuracy. Lab Questions: 1. HA(aq) + NaOH(aq) NaA(aq) + H2O 2. Trial 1: .1010 M of NaOH = moles of NaOH / 0.0299 L = 0.0030199 mols of NaOH Trial

This allows us to control a solution so that precipitation of a compound will not occur‚ or to find the concentration needed to cause a precipitate to form. The solubility product which will be determined by this experiment is that of the strong base‚ calcium hydroxide‚ Ca(OH)2.
