OCEAN 101 Lecture Notes - Lecture 1: Kosher Salt, Graduated Cylinder, Sodium Chloride
Document Summary
How can you make a salinity with a known salinity in a laboratory: materials: Kosher salt with scale in grams or milligrams. Water with a graduated cylinder with a volume in milliliters, look at meniscus. Equation to calculate salinity: 1 ppt = 1000 mg/l: 1 ppt = 1 gram/l or 1 gram/1000 ml, l = 1000 ml, 1 g = ml, subtract the amount of salt from total end volume of solution. What"s the solute and the solvent in a saline solution: solute (what is dissolved in the solution): salt (nacl) Other solutes include minerals, such as mg and so4, and gasses, such as do, carbon dioxide, nitrogen gas: solvent: water. 3 main points/takeaways: to create a solution with a known salinity, the formula needed is 1 gram/l = 1 ppt.
