What happens to the concentration as the solution is diluted?
As a solution is diluted, the concentration of solute decreases. This is because the amount of solute remains the same while the volume of the solution increases, leading to a lower concentration of the solute in the solution.
On which property of solutions does the concept of concentration rely?
The concept of concentration relies on the property of the amount of solute dissolved in a given amount of solvent. It is expressed as the ratio of the amount of solute to the total amount of solution.
What is the percent volume of ethanol?
The percent volume of ethanol in a solution is the volume of ethanol divided by the total volume of the solution, multiplied by 100. It is commonly used to express the concentration of ethanol in alcoholic beverages or solutions.
Five quantitative ways to describe the composition of solutions?
Molarity: the concentration of a solution in moles of solute per liter of solution. Molality: the concentration of a solution in moles of solute per kilogram of solvent. Mass percent: the percentage of the total mass of a solution that is contributed by the solute. Volume percent: the percentage of the total volume of a solution that is contributed by the solute. Parts per million (ppm): the concentration of a solution in parts per million by weight.
Why did chemists develop the concept of molarity?
It helps to quantify the concentration of solute in any solution - molarity is calculated by dividing the amount of solute by the total volume of the solution. The unit of molarity is moles/L.
What one what solutions contains the greatest total ion concentration?
The solution with the greatest total ion concentration will have the highest molarity of ionic compounds dissolved in it. This means it will have the highest concentration of ions in solution. Based on the principles of molarity and solubility, the solution with the most dissolved ionic compounds will have the greatest total ion concentration.

Why molarity not based on the volume of solvent alone?
Molarity is based on the total volume of the solution (solvent + solute), because the concentration of a solution is defined as the amount of solute dissolved in a given volume of the solution. By considering the total volume, we can accurately determine the concentration of the solute in the solution.
If a 25 g sample of sugar was dissolved in 50 g of water The concentration of the solution is?
To determine the concentration of the solution, we need to calculate the total mass of the solution first. The total mass is the sum of the mass of sugar (25 g) and the mass of water (50 g), which equals 75 g. The concentration of the solution is then calculated by dividing the mass of the solute (sugar) by the total mass of the solution: (25 g / 75 g) x 100% = 33.33%. Therefore, the concentration of the solution is 33.33%.
What is the final concentration of cl- ion when 250 ml of 0.20 M cacl2 solution is mixed with 250 ml of 0.40 M kcl solution?
To find the final concentration of Cl- ions, first calculate the moles of Cl- ions from each solution. Then add the moles of Cl- ions from both solutions and divide by the total volume of the mixed solution (500 ml) to get the final concentration. Using the formula C1V1 = C2V2 where C represents concentration and V represents volume, you can determine the moles of Cl- ions from each solution.
What amounts do you compare when measureing concentration?
To measure concentration, you compare the amount of the solute to the total amount of the solution.
What quantities are compared when the concentration of a solution is measured?
In science, concentration is the number of moles of solute divided by the total volume of the solution (not just the volume of the solvent). Concentration units can also include the percentage solute to the total mass of the solution; the parts per million, ppm of the solute compared to the total parts present.
What is a concentration of a solution?
Concentration of a solution refers to the amount of solute present in a given quantity of solvent or total solution. It can be expressed in various ways, such as mass/volume (g/mL), moles/volume (mol/L), or as a percentage. Concentration is important for determining the properties and behavior of a solution.
