Chemistry Lab Report on standardization of acid and bases. Purpose: To prepare standardize solution of sodium hydroxide and to determine the concentration of unknown sulfuric acid solution. Data and Calculations: This experiment is divided into two parts (Part A and Part B). In the first part of experiment‚ the standardize solution of sodium hydroxide is prepared by titrating it with base Potassium hydrogen phthalate (KHP). The indicator Phenolphthalein is used to determine that whether titration

Biological Membrane Study: HCl‚ NaOH‚ SDS Objective and Hypothesis: The objective of this lab is to determine the effects of SDS‚ HCl‚ and NaOH on red cabbage cell membrane. Prior knowledge can tell us that the red cabbage is a red-purple color due to a pigment called anthocyanin. This is what we will be testing in the experiment. We also know that HCl is a strong acid (very low pH) and that NaOH is a strong base (very high pH). From information learned in this course (lecture/lab) we can assume that both

Standardization of a NaOH Solution with Potassium Hydrogen Phthlate (KHP) Name:________________________________________________________________ Period:_____ Prelab 1. A 0.8234-g sample of "KHP" required 38.76 mL of NaOH for titration to the phenolphthalein endpoint. What is the exact molarity of the NaOH solution? 2. A 25.00-mL aliquot of an unstandardized HCl solution is titrated with the previously standardized NaOH solution from #1 above. If 32.55 mL of NaOH titrant
Premium Sodium hydroxide PH Titration
Titration Lab of NaOH and KHP Aim: To titrate Sodium Hydroxide with Potassium Hydrogen Phthalate . To also determine the concentration of NaOH in the KHP solution. Hypothesis: When KHP is added to the solution of NaOH and the indicator‚ the solution will turn clear and neutralize. The concentration of NaOH is going to be very low because it is diluted. Materials required: pipette filler‚ volumetric flasks(2-4)‚ beakers(2)‚small white piece of paper‚ indicator( 2 drops)‚ conical flask‚ clamp

LAB REPORT Introduction: In a chemical change‚ the identities of substances change and new substances form. In an equation the substances on the left are the reactants. The substances on the right are the products. In this experiment the objectives are to observe evidence that a chemical change has taken place. Infer from observations that a new substance has been formed. Identify and record observations that show energy is involved in chemical change observe the color‚ solubility of some substances
