SOLUTION AND CONCENTRATION A solution is a homogeneous mixture‚ made up of a solute dissolved in a solvent. Ex. In a water (aqueous) solution of sodium chloride‚ the sodium chloride is the solute and the water is the solvent. Solute – the component that is dissolved or is the least abundant component in the solution. Ex. Sugar‚ salt Solvent – the dissolving agent or the most abundant component in the solution. Ex. Water Common Types of Solution State of Solution State of Solute

Lab Background information: A hypertonic solution is a concentration that is higher than the solution. A Hypotonic solution is a concentration that is lower than the solution. An isotonic solution is a concentration and solution that is the same amount. Hypothesis question: What will happen if you put a potato in hypertonic solution? What will happen if you put a potato in hypotonic solution? What will happen if you put a potato in isotonic solution? Hypothesis statement: If you put sugar

Conductivity Solutions Abstract: We produced conductivity tests in water and other various solutions with a computer faced Conductivity Probe using the unit of microsiemens per centimeter (uS/cm) to find out which solutions had a high conductivity and which solutions had a low conductivity. Many different solutions vary in conductivity due to the ratio of ions. Different levels of ions have an impact on conductivity because of the different charges and different types of bonds. Conductivity is

Chapter 1 SOLUTIONS FOR EXERCISES AND PROBLEMS 1.47 Audit‚ Attestation‚ and Assurance Services Students may encounter some difficulty with this matching question because the Special Committee on Assurance Services (SCAS) listed many things that heretofore have been considered “attestation services” (long before assurance services were invented). As a result‚ we believe that this question is a good vehicle for discussing the considerable overlap between attestation and assurance services.
