11/13 notes

Question 1

precipitation reaction

Answer 1

is ionic slats in a solution. It is a reaciton in which dissolved substances react to form one or more solid products

Question 2

what does it mean when a solution is saturated

Answer 2

it means youve added enoug salt so that no more can dissolve

Question 3

Why are most salts with +1 and -1 ions soluble?

Answer 3

salts with +1 and -1 (low energy) ions are soluble because lattice enerhues are smaller in magnitude

Question 4

what are two factors affecting solubility of ionic compounds

Answer 4

-its charge and size mismatched ions

Question 5

what is arrhenius definotin of an acid

Answer 5

a substance that produces H+ in a solution.

Question 6

what is arrhenius defintion of a base

Answer 6

substance that produces OH- in a solution

Question 7

difference between diproyic nd miniprotic acid is

Answer 7

diprotic has two H+ ions and monoprotic has 1 H+ ion

Question 8

what are the three common strong acids

Answer 8

hydrophobic acid (monoprotic) nitric acid (monoprotic) and sulfuric acid (diprotic)

Question 9

What makes an acid or base “strong” or “weak”?

Answer 9

strong acid will produce H+ ion in a solution and weak acids do not produce a lot of H+. A base is strong when it produces metal hydroxides ie Na and Oh. A weak base has ammonia as reactant

Question 10

what is a neutralization reaction

Answer 10

an acid and base that goes to salt and water (if base is a carbonate or bicarbonate, CO2 gas is also produced)

Question 11

spectator ions do what

Answer 11

nothing (ones that are not part of precipitate)

Question 12

why do size mismatched ions tend to be soluble because

Answer 12

they cannot pack together well to firm a lattice
