How Can We Accurately Make Different Solutions of Different Concentrations?

What happens when you combine 6.022 times 10 to the 23 piles of dirt into one? You make a mountain out of a mole hill. Scholars use dehydration to obtain percent composition and then calculate the molarity of the original solution. 

Teach the process of calculating concentrations of a solute. The fourth in a series of seven chemistry lessons shows the various types of calculations including grams per liter, molarity, parts per million, and percent composition. The...

How well can your class concentrate on solutions? Scholars use colorimeter absorption to explore a starch concentration calibration curve. They add iodine to different starch solutions to see how the concentration of the solution changes.

When no more solute can be dissolved into a solvent, the solution has reached saturation. The interactive simulation allows learners to manipulate a solution in order to measure its concentration. The amount of solvent, the amount and...

Learners, through watching a simulation, can manipulate various characteristics of different solutions focusing on acid-base solutions where pH, strength of solution, and concentration may be changed. Views may be at the molecular level,...

Ready to teach your class about molar mass and solution concentration? Make time for an interactive resource that will challenge their reasoning and problem-solving skills. Science scholars calculate the molarity of several solutions...

Does a concentrated solution or a diluted solution contain more particles? The 24th video in a 30-part series answers this question as an introduction to figuring concentration using the standard formulas. Through two different formula...

Ionic bonds form from electrostatic energy, allowing for higher conductivity than those seen in covalent bonds. In the simulation, learners add sugar and salt to water and see the effects on concentration and conductivity of their...

The human immune system doesn't always prevent us from getting sick, so what is it doing? Young scientists watch a short video explaining what the immune system is and how it works. Then, they answer eight questions to prepare for an...

Watch your solution change color as you mix chemicals with water. Then check molarity with the concentration meter. What are all the ways you can change the concentration of your solution? Switch solutes to compare different chemicals...
