Acids and Bases

Question 1

What do Aqueous solutions of acids taste like? (Throwaway)

Answer 1

Aqueous solutions of acids have a sour taste

Question 2

What do acids and bases change the color of?

Answer 2

Acid base indicators (throwaway)

Question 3

What do some acids react with to produce H2?

Answer 3

Active metals

Question 4

What happens when acids and bases react?

Answer 4

Produces salts and water

Question 5

Do acids conduct electric current?

Answer 5

yes

Question 6

Acid nomenclature–binary acid

Answer 6

contains only 2 diff elements–H and one of the more electronegative elements

Question 7

More electronegative elements

Answer 7

HF, HCl, HBr, HI

Question 8

Naming a binary acid

Answer 8

prefix hydro, root of name of second element follows prefix, ends with -ic

Question 9

oxyacid

Answer 9

acid compound of H, O, and third element *(usually non metal)

Question 10

dissociation

Answer 10

when two ions separate in aqueous solution

Question 11

Naming oxyacid

Answer 11

follows a pattern; names of anions based on names of acids

Question 12

What does an acid always produce when it dissociates? What does this tell you about the other product?

Answer 12

An acid always produces H+ ions when it dissociates–this can tell you the other product’s charge, because you can isolate the charge of the reactants and subtract the H+ ions from it once the equation is balanced.

Question 13

If the suffix of an anion of an acid is -ate, what is the acid name suffix?

Answer 13

ic

Question 14

If the suffix of an anion of an acid is -ite, what is the acid name suffix?

Answer 14

ous

Question 15

Common industrial acids

Answer 15

Sulfuric, Nitric, Phosphoric, Hydrochloric/muriatic, Acetic

Question 16

What do Aqueous solutions of basis taste like? (Throwaway)

Answer 16

bitter

Question 17

What do dilute aqueous solutions of bases feel like?

Answer 17

slippery (God, these are stupid questions.)

Question 18

Do bases conduct electricity?

Answer 18

yes

Question 19

Arrhenius acid

Answer 19

chemical compound that increases concentration of H+ ions in aqueous solution (molecular compounds w/ ionizable H atoms)

Question 20

Ionization

Answer 20

Ionization is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons to form ions, often in conjunction with other chemical changes. (Wikipedia, but true. I just didn’t have words.)
