What else can I help you with?
50 g of potassium chloride (KCl) are added to 100 mL of water. All but 10 g of the KCl dissolves. Which equilibrium situation becomes established in the resulting solution?
The remaining 10 g of KCl forms a saturated solution in water, meaning the solution is in dynamic equilibrium with solid KCl dissolving and KCl ions re-crystallizing at the same rate. The resulting solution will contain both dissolved K+ and Cl- ions in equilibrium with undissolved KCl crystals.
Rocks that contain crystals exhibit what texture?
Rocks that contain crystals exhibit a coarse texture. The crystals within the rock are generally large enough to be seen with the naked eye, giving the rock a grainy appearance.
Does molten rock contain large crystals?
Completely molten rock would not contain any crystals. Most magmas, however, are a mixture of molten and solid crystals of some sort. It is possible that a magma could contain larger crystals of a specific mineral.
Why can't you use vacuum filtration for filtering a hot saturated solution?
The lower pressure of the suction flask would cause the filtrate to boil. If this happened, the material in solution would be deposited over the walls of the flask.(From Techniques and Experiments for Organic Chemistry by Addison Ault)
Does tuff have crystals?
In some cases it does contain crystals that formed prior to the eruption.
How is an aqueous solution of table salt different from an aqueous solution of table sugar descibe how each solution forms?
An aqueous solution of table salt (sodium chloride) forms when salt crystals are dissolved in water. The salt crystals dissociate into sodium (Na+) and chloride (Cl-) ions in the water. An aqueous solution of table sugar (sucrose) forms by dissolving sugar crystals in water. The sugar molecules do not dissociate into ions in water like salt does, but rather stay intact as individual sugar molecules.
What is the saturation point of sodium chloride?
At 20 0C a water solution with a sodium chloride concentration higher than 36,09 g/100 ml is a saturated solution.
Do all crystals contain water in crystallization?
no
Do metamorphic rocks contain lectures crystals?
yes
What are two extrusive igneous rock that contain crystals?
Basalt and rhyolite both are extrusive igneous rock that contains mineral crystals. However, the mineral crystals are normally less than 1 mm in diameter, and are therefore not discernible without magnification.
Do extrusive igneous rocks contain crystals?
No. Pure volcanic glasses contain no crystalline structure.
What does a weak solution contain?
it contain solvent
