If I have 0.075 m A true story. Standards. Science: Chemistry . 6.d. Students know how to calculate the . concentration . of a . solution.. Investigation and Experimentation. . 1a. Select and use appropriate tools. What are serial dilutions?. Also called a “dilution series”, serial dilutions are, essentially, . dilutions of dilutions. .. Why do we need serial dilutions?. This flask contains 10 mg/mL Green Fluorescent Protein (GFP)*. Solution Preparation. How do we create chemical solutions in a laboratory setting with a certain concentration/molarity? . Obtain the mass of the chemical compound serving as solute. Dissolve the solute in a small amount of the solvent. Chapter 7.3. Objectives. Explain the meaning of solubility and compare the solubility of various substances.. Describe dilute, concentrated, saturated, unsaturated, and super-saturated solutions.. Relate changes in temperature and pressure to changes in solubility of solid and gaseous solutes.. Intro to Spectrophotometry. Solutions. Solution: . a homogenous mixture of two or more substances in the same phase.. Solute: . substance dissolved in another substance (the solvent). Solvent: . substance that dissolves a solute, resulting in a solution. Solutions Expressed as percent. The term . percent. . is Greek for . per 100. . When concentration is expressed in terms of percent, the numerator is the amount of solute and the denominator is 100 units of total solution.. Director of Research.

Water as a . Polar Solvent. Water is a polar molecule. since it has uneven electron distribution . and a bent molecular shape.. Due to its polar nature, water interacts strongly with its solutes and often plays an active role in aqueous reactions.. Solutions are classified as mixtures.. The a. mounts of substances mixed (solute and solvent) can vary in different solutions.. Concentration. is a way of communicating how much solute is dissolved into a given amount of solution.. . a.
