The purpose of this experiment was to observe the hypothesized correlation between ionic strength and degree of ionization of a weak acid‚ while determining the factors that would impact the degree of ionization using measurements of pH. It was initially required to prepare standard 20-mL solutions of varying concentration of acetic acid for use in the rest of the experiment. One solution of CH3COOH was supposedly developed to be 2.00M‚ however it is highly possible that the solutions of CH3COOH

Lab of Determining an Empirical Formula B2 Honors 12/18/13 Abstract In this lab‚ to help better understand the concepts of gram atomic masses and empirical formulas‚ we found the gram atomic masses and empirical formula of a binary compound. The two compounds should form a definite whole number ratio by mass. This ratio will also help determine the subscripts of the elements in the empirical formula. Errors in this experiment can stem from measuring wrong or doing equations incorrectly.

Sean Dowling Julia Phaltankar Mrs. Oakes Chemistry w/ Algebra 10/G February 18‚ 2015 Determining Empirical Formula Lab Introduction: One can find an empirical formula by taking a sample of a compound and dividing the number of moles of one element in the compound by the number of moles of another element in the compound to form a small wholenumber formula. For example‚ in a sample of a made up compound of oxygen and lead‚ one mole of lead has a molar mass of 207.2 g/mole‚ and oxygen

The amount of a certain type of substance‚ in mole that can be calculated accurately from their mass are called primary standards due its purity. Primary standards should be always readily obtainable in pure form. It also should also have a known formula and be simple to put away without deteriorating or reacting with the atmosphere. It is also preferable that the substance have a high molar mass in order to decrease the effect of errors in weighing. A primary standard can be used to prepare a standard
