Name: Sebastian Sak Lab Partners: Tim Gronet TA: Feifei Xu Determining Molar Enthalpy of Dehydration of Sodium Acetate Trihydrate Purpose: In this lab, two solid substances, sodium acetate and sodium acetate trihydrate, will be analyzed for the heat of solution for both processes. This allowed the calculation of the molar enthalpy of dehydration of sodium acetate trihydrate. Calorimetry was used to experimentally determine the heat of solution for both reactions. Procedure: This lab was…

This experiment will allow us to determine the molar mass of the unknown solute through calculating the difference in freezing point of the pure solvent and the solution with the unknown solute. This lab will show case one of the colligative properties of a solution. This property is dependent upon the number of solute molecules or ions and not the identity or chemical property of the solute. A common example is water which both freezes and melts at 0°C no matter the amount of water or the size…

experiment was to prepare and standardize a sodium hydroxide solution as well as determine the molar concentration in as strong acid and the percent by mass of acetic acid in vinegar. We used volumetric analysis, also known as titration, in both experiments. The average molar concentration for NaOH was 0.2749 mol/L while the average molar concentration of the acid solution was .2493 mol/L.The average percent by mass of acetic acid in vinegar was found to be 12.3 % Introduction: The Purpose of…

Observe • Learn how to utilize and understand the functioning of the pH meter. • To find a stoichiometric point using a functional graphical method. • To discern the molar concentration of a specific weak acid solution. • To compute the molar mass of a specific weak acid utilized within the experiment. • To calculate the pKa of a weak concentrated acid within the experiment. Procedure 1. Molar Concentration of a Weak Acid Solution • Obtain an unknown acid solution (90 mL) and three 250 mL…

The figures 11-15 represent the different aspects of the left Permanent Mandibular Second Molar. Mandibular molars are the largest teeth on the mandibular arch. There is a number of three on each side of the mandible; first, second and third mandibular molars. They resemble each other in functional form, although when in comparison with each one, it’s clear the variations in the number of cusps, size, the occlusal design and the lengths and position of the roots. All mandibular molars have…

The goal of this lab was to find the molar sucrose concentration at equilibrium. Which is when the potato core and the sucrose solution reach equilibrium, so that no water is entering or leaving the cell. After collecting the data, the line of best fit never crossed the x-axis or showed where the molar sucrose concentration at equilibrium. I had to extrapolated the point at which it crossed the x-axis. This led to the data being unreliable because there is no physical evidence present that…

Molar Volume of a Gas Lab The purpose of the lab was to do an experiment to determine the molar volume of hydrogen gas at standard temperature and pressure, or STP. To start the experiment, a beaker was filled with water and then a cage was created with a copper wire. A piece of magnesium was cut and placed inside the cage in order to keep the reaction going until all of the magnesium reacted with the hydrochloric acid. The eudiometer tube was filled with 15 mL of hydrochloric acid and water…

Figure 1 shows the relation between density ρ and molar volume Mv as a function of copper oxide. From this figure, can be observed that the ρ and Mv decreased with the increased of copper oxide content replacement the lead oxide. The decrease of density due to the molecular weight of CuO is lower than the molecular weight of Pb3O4. The decrease of the molar volume due to the decrease the number of oxygen and may be the ionic radius of copper ions less than the ionic radius of lead ions. The…

When trying to measure the 0.250 molar solution (of which is in water and sodium phosphate solution) in 500 mL, there are very specific steps in which you need to follow. Pouring the correct amount of the solution in the beakers is important, as to make sure that the solution is not over concentrated, or under concentrated. if you were to use a flask that had a different volume amount, and filled that flask up to (for example one flask with five hundred milliliters.) the full amount,the solution…
