Van't Hoff factor (i) measures solute's impact on solution's colligative properties. It's the ratio of particles formed to moles of initial formula units. Formula: i = moles of particles/moles of solute dissolved. Can be expressed as i = 1 + α(n - 1)
Molarity (M) is moles of solute per liter of solution. Solutions can be prepared by dissolving solids or diluting liquids. Percent solutions express solute as grams per 100 grams of solution
Studied hormone treatment of dim sicknesa using clortisone and prednisone. Researched plutonium metabolism and its effects on gastrointestinal tract. Developed methods for monitoring plutonium in gastrointestinal tract. Researched effects of lithium salts on plutonium metabolism
Systems are classified as homogeneous or heterogeneous based on physical characteristics. A phase is a distinct portion of a system maintaining same properties. Three main phases exist: solid, liquid, and gas
Suspension is a heterogeneous mixture containing particles larger than 1 micrometre. Particles are visible to naked eye and do not settle. Particles remain suspended in bulk throughout the mixture. Suspensions are opaque and can be separated using filtration. Examples include oil in water, muddy water, and dust in air
