Groundwater would be water that is in the ground, but not from it. As the definition says, the water is from precipitation from the sky that infiltrated into the ground and became ground water.Could you explain more about your thought process? Sorry, I'm still not understanding why you cannot say "Groundwater is water from the ground."
I assume you are making your salinometer for a solution of 100 mL. I would recommend using a 100mL graduated cylinder to start building your salinometer. You'll need an electronic balance, a stirring rod, a beaker of some sort, salt, and a straw with clay on the end of it (this will be your salinometer) First you weigh out, for example, 10 grams of salt (usually NaCl) using the electronic balance. Then, deposit that salt into the beaker. Use the beaker to transfer the salt in turn into the graduated cylinder. Fill the graduated cylinder with water until the volume is at 100 mL. Stir until all salt particles have been dissolved in the graduated cylinder. The resulting solution in this case would be a 10% salt solution. Place the salinometer clay end facing into the water. The water level at the top of the graduated cylinder should be on a spot on the body of the straw. Mark this level, and repeat these above steps when trying to get different percentages of salt concentration.Hi can someone explain to me how you make a correct salt solution for my salinometer.
Hey there. So, the salt solutions which you will encounter in water quality will range from 1% to 10% in salinity. Salinity is the concentration of salt, in this case NaCl (if the term changes for different salts, someone correct me). Percentage is a nice easy calculation. It is the grams of NaCl divided by each 100 ml of water. That means, in order to make a 1% salinity solution, you need to measure out 1 gram of NaCl and dissolve it into 100 ml of water. Same idea for the other percentages. I typically place a piece of circular filter paper onto an electronic balance, zero it out, and place my salt on that so I can easily remove it.Hi can someone explain to me how you make a correct salt solution for my salinometer.
Sorry if someone answered your question that I didn't notice, but for indicator studying I use quizlet a lot. If you need specific links, I can give them to youHey, anyone have any sites for the organisms as indicators of water quality?
