How are conductivity and concentration of a salt solution related?
The greater the concentration of salt in an aqueous solution, the higher the electrical conductivity. This is because, with a greater salt concentration, there are more ions available to serve as a path for electron transfer in the solution.
Why molality is not temperature dependent?
Molarity is the no of moles of solute per dm3 solution, the temperature change changes the volume so molarity becomes effected.
What does concentration mean in chemistry?
Concentration relates the amount of solute to the amount of solvent. For instance, in a salt water solution, salt is the solute and water is the solvent. A way to measure the concentration of a chemical would be molarity or M. The molarity stands for the moles of solute in the liters of solvent.
How is a hypertonic solution different from a hypotonic solution?
Hypotonic solution has much less particles dissolved inside the solvent than there is in the cell floating in the mixture. A hypertonic solution has a greater concentration of particles dissolved in the solvent than inside the cell.
What is made by adding 4.5 moles of NH3 to 250ml of water.what is the molarity?
Adding 4.5 moles of NH3 to 250 mL of water will result in a solution with a volume slightly greater than 250 mL. To calculate the molarity, you need to know the final volume of the solution. Once you have the final volume, you can use the formula: Molarity = moles of solute / liters of solution.
Is the lower the molarity the higher the concentration or the lower the molarity the lower the concentration?
The lower the molarity, the lower the concentration. Molarity is a measure of the concentration of a solute in a solution. A lower molarity means there is less solute dissolved in the solution, resulting in a lower concentration of the solute.
What is the difference between a concentration and a dilute?
A concentrated acid has more acid than water and a dilute acid has more water than acid. True facts, otherwise known as its molarity. The greater the molarity the more concentrated it is (moles of acid/ liter of solution)
How do you decide which of a group of solutions has the greatest concentration of hydroxide ions OH-?
Determine the concentration of hydroxide ions by looking at the molarity of the base in the solution. A higher molarity of the base will result in a greater concentration of hydroxide ions. Use stoichiometry to calculate the concentration of hydroxide ions based on the balanced chemical equation for the reaction.
If the solute concentration of a solution is increased how does that affect the water concentration of that solution?

When comparing two solutionsthe solution with the greater concentration of solute so is called?
When comparing two solutions, the solution with the greater concentration of solute is called hypertonic. This means that it has a higher solute concentration compared to the other solution.
How are conductivity and concentration of a salt solution related?
The greater the concentration of salt in an aqueous solution, the higher the electrical conductivity. This is because, with a greater salt concentration, there are more ions available to serve as a path for electron transfer in the solution.
Why molality is not temperature dependent?
Molarity is the no of moles of solute per dm3 solution, the temperature change changes the volume so molarity becomes effected.
Which solutions has a greater concentration of hydroxide ions a solution of pH 3 or a solution of pH 9?
A solution with a pH of 9 has a greater concentration of hydroxide ions than a solution with a pH of 3. The pH scale is a logarithmic scale, with each unit representing a tenfold difference in hydrogen ion concentration. Therefore, a solution with a pH of 9 has a concentration of hydroxide ions 1,000 times greater than a solution with a pH of 3.
What is the relationship between the percentage change in mass and sucrose molarity?
Change in mass depends on the concentration of sucrose within the dialysis bags. If the concentration of sucrose is greater inside the bag than outside, then water will move into the bag. If the concentration of sucrose is lower inside the bag than outside, then water will move out of the bag.
What does concentration mean in chemistry?
Concentration relates the amount of solute to the amount of solvent. For instance, in a salt water solution, salt is the solute and water is the solvent. A way to measure the concentration of a chemical would be molarity or M. The molarity stands for the moles of solute in the liters of solvent.
What solution has a grater concentration h or OH?
A solution with a greater concentration of H+ ions has a lower pH value, indicating an acidic solution, while a solution with a greater concentration of OH- ions has a higher pH value, indicating a basic solution. The concentration of H+ and OH- ions in a solution are inversely related in water, following the equation: [H+][OH-] = 10^-14 at 25°C.
The concentration of material is greater on the outside of the cell than the inside in what solution?
The concentration of material is greater on the outside of the cell than the inside in a hypertonic solution. In this solution, there is a higher concentration of solutes outside the cell compared to inside, causing water to move out of the cell, leading to cell shrinkage.
