What does like dissolves like mean quizlet?

“Like dissolves like” means polar solutes are more soluble in polar solvents and nonpolar solutes are more soluble in nonpolar solvents. A solute will be most soluble in a solvent that generates intermolecular forces similar in strength to its own.

Like dissolves like” is an expression used by chemists to remember how some solvents work. It refers to “polar” and “nonpolar” solvents and solutes. Basic example: Water is polar. Oil is non polar. Like dissolves like, that means polar dissolves polar, so water dissolves salt.

One may also ask, how does soap work quizlet? the likes attract the likes and the nonpolar tail sticks to the nonpolar grime. the polar head is attracted to water. as water is washed away the soap pulls out the grime.

Consequently, what specific feature of chemical substances do we refer to when we say like dissolves like?

In chemistry, the “like dissolves like” rule refers to solubility and polar and non-polar substances. Remember: “Solute” means the substance that is dissolved into a larger substance (the solvent).

What is the principle of like dissolves like?

In general, “Like dissolves like“, describes the general principle of solubility (i.e. polar solvents dissolve polar solutes and non-polar solvents dissolve non-polar solutes). However, a polar liquid and a nonpolar liquid are immiscible. They repel one another and separate into two layers.

What is an example of like dissolves like?

“Like dissolves like ” means if any substance is polar then polar and ionic substances will be dissolved in it. Example : HCl in water. If the solvent is non-polar then the non-polar substances only can be dissolved in it. Example : hexane in benzene.

What do you mean by dissolving?

verb (used with object), dis·solved, dis·solv·ing. to make a solution of, as by mixing with a liquid; pass into solution: to dissolve salt in water. to melt; liquefy: to dissolve sugar into syrup.

What dissolves in oil but not water?

Petrol is a non-polar solvent and will dissolve oil, but will not mix with water.

What is Desolve?

By Vangie Beal In graphics and video editing dissolve is a term used to describe a transition effect in which one video clip (or one image) is gradually fads out while another image simultaneously replaces the original one.

Is wax polar or nonpolar?

Paraffin waxes are insoluble because of its non-polar characteristic. All alkanes are non-polar in nature. And since we always say that “like dissolves like”, water being a polar molecule, cannot dissolve paraffin waxes.

Is h2o polar or nonpolar?

A water molecule, abbreviated as H2O, is an example of a polar covalent bond. The electrons are unequally shared, with the oxygen atom spending more time with electrons than the hydrogen atoms. Since electrons spend more time with the oxygen atom, it carries a partial negative charge.

What happens when NaCl dissolves in water?

Sodium chloride (NaCl) dissolves when water molecules continuously attack the NaCl crystal, pulling away the individual sodium (Na+) and chloride (Cl–) ions. This nonstop attack continuous until the whole NaCl crystal disintegrates.

How do substances dissolve?

A solute dissolves because its particles interact with the particles of a solvent. Anything that allows more solvent to touch more solute will cause a solute to dissolve more quickly. Small pieces of a substance dissolve faster than large pieces.

What is the formula for solubility?

Solubility indicates the maximum amount of a substance that can be dissolved in a solvent at a given temperature. Such a solution is called saturated. Divide the mass of the compound by the mass of the solvent and then multiply by 100 g to calculate the solubility in g/100g .

How do you test for solubility?

Add 1 drops of a liquid sample or about 25 mg of a solid sample to 0.5 mL of distilled or deionized water in a test tube. Tap the tube with your finger to mix or stir gently with a glass stirring rod. Record the sample as soluble or insoluble. If the unknown is water-soluble, test the solution with pH paper.

What happens when c6h12o6 is dissolved in water?

C6H12O6 (s) + H2O (l) → C6H12O6 (aq) If we dissolved any substance in water,it would be formed into it’s aqueous solution. Here we dissolved glucose in water. After mixing there formed aqueous solution of glucose.

Is NaCl polar or nonpolar?

Yes, NaCl is an ionic bond which makes it polar. A polar molecule consists of atoms having either a positive or negative bond. Polar molecular bonds consist of atoms having a partial positive or partial negative charge, as molecular bonds usually only consist of nonmetals. However, ionic bonds are always polar.

What affects solubility?

Solubility is the maximum amount of a substance that will dissolve in a given amount of solvent at a specific temperature. There are two direct factors that affect solubility: temperature and pressure. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of gases.

Why is water called the universal solvent?

Water is capable of dissolving a variety of different substances, which is why it is such a good solvent. And, water is called the “universal solvent” because it dissolves more substances than any other liquid. This allows the water molecule to become attracted to many other different types of molecules.
