Answer 4

Only partially dissociate when dissolved in water, including weak acids and bases

Question 5

Nonelectrolytes

Answer 5

Substances that dissolve in water but do not dissociate, such as covalent compounds

Question 6

What are the 4 rules for how we know an ionic compound is soluble?

Answer 6

Group 1A metal ions, ammonium ions, nitrate ions, acetate ions

Question 7

Precipitation reaction

Answer 7

A reaction in which Ions in a solution regenerate an ionic solid(opposite of dissociation)

Question 8

Molecular equation

Answer 8

An equation that does not show all soluble ionic compounds as ions

Question 9

Ionic equation

Answer 9

An equation that shows all soluble ionic compounds as ions

Question 10

Net ionic equation

Answer 10

An equation that includes only those compounds and ions that undergo a chemical change in a reaction in an aqueous solution

Question 11

Acid

Answer 11

A substance that when dissolved in water increases the concentration of H+ ions

Question 12

Bases

Answer 12

A substance that when dissolved in water increases the concentration of OH- ions

Question 13

Neutralization reaction

Answer 13

Reaction between a strong acid and a strong base that produces a salt

Question 14

Salt

Answer 14

Ionic compound where a cation comes from a base and an anion comes from and acid

Question 15

Molarity

Answer 15

Moles of solute per liter of a solution

Question 16

4 steps for making a solution from a solid solute

Answer 16

1Determine mass of solute needed to make the solution you’re trying to make
2Transfer solute into volumetric flask
3Fill volumetric flask half full with distiller water and dissolve solid by stirring
4Add enough distilled water till the fill line and use a pipette for the excess

Question 17

4 steps for diluting concentration solids

Answer 17

1Determine volume of concentrated solution needed to be diluted based on molarity trying to be achieved
2half fill the appropriate sized volumetric flask with distilled water. Add your volume you got of the concentrated solution to water and swirl
3Fill the volumetric flask to the fill line with distilled water and use pipette for excess
4Cap and invert to mix

Question 18

How to find volume of concentrated solution

Answer 18

McVc=MdVd
Mc is molarity of concentrated solution and Vc is volume
Md is molarity or diluted solution and Vd is volume
