CHM/BCH 3120: Analytical Chemistry

This video tackles the classification of boiling water as either a physical or chemical change, examining the provided options. We conclude that boiling is a physical change, as the water's chemical composition remains the same during the transition from liquid to gas.

This video breaks down the configurations for In In+ In2+ and In3+ distinguishing between diamagnetic and paramagnetic properties. Uncover the oxidation state of Indium in InCl2 and understand its diamagnetic nature.

Explore the intriguing process of determining the vapor pressure of a urea-water solution at 35°C. Using Raoult's law we'll calculate the mole fraction of water and urea leading to the solution's vapor pressure. Learn how the solution's composition affects vapor-pressure lowering

In this video we explore the process of calculating the weight percent of barium potassium and chlorine in a mixed sample of barium chloride dihydrate and potassium chloride. Through a step-by-step approach we examine the changes in sample weight after heating to 160°C breaking down the calculations for each elemental content.

Converting Denver's average pressure of 24.9 in. Hg into various units. This video provides clear steps to determine equivalents in millimeters of mercury atmospheres pounds per square inch and pascals. Understand the relationships and conversions between these common pressure units.

In this analysis, we determine the composition of a solution prepared by dissolving 12.15g of nickel(II) nitrate in 175mL of water (density 1.00 g/mL). The mass percent of nickel(II) nitrate is found to be approximately 6.50%, and the mole fraction of nickel(II) ions in the solution is calculated as 0.00672.
