PPT-Dilutions

An Introduction Activity overview In this activity you will visualize what is meant by a dilution You will also examine how to express the dilution that has been made Part I Dilutions made with food coloring. The following is a brief explanation of some ways of calculating dilutions that are common in biological science and often used at Quansys Biosciences Using C C To make a fixed amount of a dilute solution from a stock solution yo u can use the form 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. Mix 2 solutions together…. …they both get diluted.. It’s ping pong balls in a bucket…. 5 gallon bucket - Ping pong ball. 5 gallon empty bucket - 5 Ping pong ball. Add 1 gallon of water. What’s the “concentration of ping pong balls”?. Solution Preparation. How do we create chemical solutions in a laboratory setting with a certain concentration/molarity? .

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..
