Standardize a sodium hydroxide solution by using potassium hydrogen phthalate (KHP) III. When given whether the acid is monoprotic‚ diprotic‚ or triprotic ‚ determine the molar mass of the unknown organic acid. IV. Calculate the Molarity of the Soft drink.

Experiment #5: Acid Burn!!! Introduction The goal of this lab was to correctly prepare a 0.2M solution of NaOH‚ identify highly acidic household cleaning chemicals‚ and determine their concentration (molarity) through titrations using the previously prepared 0.2M NaOH solution. Experimental First‚ to create 0.5L of 0.2M solution of NaOH‚ standard 3M NaOH solution was obtained. Next‚ calculations were performed to determine the amount 3M NaOH necessary to create 0.5L of the 0.2M solution and‚ as

AMINO ACIDS BY MEANS OF TITRATION CURVE ABSTRACT The aim of the experiment was to identify an unknown amino acid through acid-base titrations which was prepared in water to form an acidic solution. Each group prepared unknown amino acid hydrochloride. The pre-prepared basic solution was slowly added to the amino acid solution and pH change was closely observed using the pH meter. During these titrations the amino acid converted from cation to zwitterion to anion; zwitterion is an amino acid with

For this week’s assignment in PCN-525‚ counselors are asked to choose a particular instrument which measures a psychological-personal characteristic. This counselor’s choice would be Myers-Briggs Type Indicator (MBTI). This assessment tool is a psychometric set of questions that looks at how we make decisions based on our perception of the world. This assessment was originally developed by a mother and daughter team that had studied the work of Carl Gustav Jung. They took Jung’s theory of four domains

1.0 Aim The purpose of this experiment is to use Volumetric Analysis to determine the concentration of acetic acid in white vinegar. 2.0 Theory The concentration is a measurement of relative amounts of solute and solvent. There are many diverse ways of expressing concentration but the most accepted and widely used is molar concentration and regularly referred to as molarity which is defined in mole‚ the amount of solute dissolved in one litre of solution.

are several purposes to the amino acid lab experiment. One reason is to help us understand the concept of acids and bases and how they interact with one another. Another purpose is to understand what occurs when placed with the existence of buffers. Lastly‚ the experiment is to help us understand the applications of titrations and how it can be used in a real world setting‚ in this case‚ the identification of an amino acid. One must understand that amino acids all have special characteristics

Melting pointe determination #01 Introduction: Objective To learn how to obtain an accurate melting point using a MELTING POINT APPARATUS‚ then use them to draw eutectic curve and determine the eutectic point. Melting point of a solid is the temperature at which the solid and its liquid form are in equilibrium‚ i.e.‚ molecules move back and forth between the two states at the same rate‚ so both phases remain present. If the temperature of a solid is measured carefully as the solid is heated
