Rate of Dissolving
Heating a solvent generally does this to the rate at which a solid solute dissolves.
What is increases it (or speeds it up)?
Water is often referred to as the "Universal Solvent" primarily because its molecules possess this property.
What is polarity (or being polar)?
In a beaker containing a mixture of Kool-Aid powder dissolved in water, the water acts as this component.
What is the solvent?
During a chemical reaction, an insoluble solid that forms and settles out of an aqueous solution is known as this.
What is a precipitate?
In the formula for molarity, this is the unit used for Volume.
What is Liters?
Crushing a large chunk of solute into a fine powder increases this, leading to a much faster dissolving rate.
What is surface area?
A nonpolar solute will be able to dissolve in what type of solvent?.
What is a nonpolar solvent?
If you drop a single crystal of sugar into a solution and the crystal completely dissolves, the original solution was at this saturation level.
What is unsaturated?
When Potassium Iodide (KI) reacts with Lead(II) Nitrate (Pb(NO3)2), these are the two products formed, and this specific one is the solid precipitate.
What are Potassium Nitrate (KNO3 - soluble) and Lead(II) Iodide (PbI2 - precipitate)?
This is the calculated molarity of a solution if you dissolve 6.0 moles of NaCl in 2.0 Liters of water.
What is 3.0 M?
Stirring or agitating a solution makes a solid dissolve faster because it continually brings fresh amounts of this into contact with the solute.
What is the solvent?
A substance, such as sodium chloride, that breaks apart into mobile ions and conducts electricity when dissolved in water is known by this term.
What is an electrolyte?
When a solution holds the absolute maximum amount of dissolved solute possible at a specific temperature, it has reached this state.
What is saturated?
Mixing aqueous solutions of Magnesium Sulfate (MgSO4) and Barium Chloride (BaCl2) yields these two products, with this one dropping out as the solid precipitate.
What are Magnesium Chloride (MgCl2- soluble) and Barium Sulfate (BaSO4 - precipitate)?
To prepare 500 mL of a 1.0 M solution using a 5.0 M highly concentrated stock solution, you must measure out exactly this volume of the stock.
What is 100 mL?
Unlike solid solutes, gases dissolve best in liquids under this specific temperature condition.
What is cold (or low temperature)?
Because a well-mixed saltwater solution looks completely uniform throughout and does not settle, it is classified as this type of mixture.
What is a homogeneous mixture?
According to typical solubility graphs, as the temperature of a liquid solvent increases, the amount of solid potassium chloride that can dissolve does this.
What is increases?
Reacting Sodium Hydroxide (NaOH) and Copper(II) Sulfate (CuSO4) yields these two products, and this specific one is the insoluble precipitate.
What are Sodium Sulfate (Na2SO4 - soluble) and Copper(II) Hydroxide (Cu(OH)2 - precipitate)?
You have 100 mL of a 4.0 M solution. If you dilute it until the new volume is 200 mL, this will be your new molarity.
What is 2.0 M?
While a scuba diver descending in water or a sealed soda bottle experiences this, it only increases the solubility of gases, not solids.
What is high pressure?
If a substance dissolves perfectly in water but will not dissolve in oil, the substance must have this chemical nature.
What is polar (or ionic)?
If you drop a seed crystal into a solution and a massive amount of excess solute rapidly crystallizes out of the liquid, the original solution was at this unstable state.
What is supersaturated?
If you mix aqueous solutions of Ammonium Chloride (NH4Cl) and Sodium Nitrate (NaNO3), these are the predicted products and their states of matter.
What are Ammonium Nitrate (NH4NO3) and Sodium Chloride (NaCl), and BOTH are aqueous/soluble (meaning no precipitate forms / no reaction occurs)?
To successfully create 3.0 Liters of a 1.5 M solution of ammonium nitrate, you would need exactly this many moles of the solute.
What is 4.5 moles?
