Matter: Solutions And Solubility Review

Solubility

Dissolving a polar substance in water

Water is dissolved into n-butanol (a polar liquid). Which is the second step at the molecular level as water dissolves into n-butanol?

The table shows four samples of carbon dioxide and the temperature of the water that they dissolved in. 1 - 78 degree's 2 - 73 degree's 3 - 55 degree's 4 - 63 degree's

Increasing the solubility of gas

A solution was made by completely dissolving 1200 g of table salt into 3 L of hot water. Then, the water was left to cool to room temperature. If the solubility of the salt is 36 g/100 mL water, which term best describes this solution at room temperature?

Which is true about dissolving process in water?

What is the solubility of Na2HAsO4 at 60°C?

Which of these factors will cause a solid solute to dissolve faster?

Which factor influences both solubility and the rate of dissolution?

A chemist dissolved crystals of an unknown substance into water at room temperature. He found that 33 g of the substance can be dissolved into 100 mL of water. What property of the unknown substance was the chemist most likely investigating?

A beaker contains a solution. A single solute crystal is added to the solution. Immediately, crystals form in the solution. Which term best describes the solution before the crystal was added?

A student wants to dissolve a large piece of salt into distilled water. He breaks the salt into two smaller pieces and adds it into the water. He stirs the mixture at a constant speed and continually adds more heat until all the salt is dissolved. Which factor most likely had the greatest effect on increasing the rate of dissolution?

A student is repeating an experiment that involves dissolving a sugar cube in water. In her second trial, she uses a larger beaker and adds more water. She also crushes the sugar cube into finer crystals, as well as increases the amount added to the water. Given that the student is not preparing a saturated solution, which factor will affect the rate at which the sugar dissolves?

Under which conditions will sugar most likely dissolve fastest in a cup of water?

Which statement accurately describes part of the dissolving process of a polar solute in water?
