Excess crystals KCr,0, Crystals of K2Cr207 are added to water and dissolved until a large excess of crystals sink to the bottom of the container. Which of the following are true the diagram above? [Check any that are true statements.] The orange liquid is a saturated solution. The solution can be made more concentrated by adding more crystals. O Adding a small amount of water to dissolve a few of the excess crystals will decrease concentration. O Adding a twice the amount of water needed to dissolve the excess crystals will lower the concentration. OEvaporating some water will cause more crystals to appear. but the concentration will not change. Adding more crystals will darken the orange color of the liquid.
