Question

Choose whether the description applies to acids only, bases only, or both.

Taste bitter

pH greater than 7

pH less than 7

good conductors [electrolytes]

react vigorously with metals

Feel slippery

Taste sour

Answer 1

this is going to take some time for me...

taste bitter... a property of (some) bases, according to chem: the central sci

Answer 2

taste sour or tart... acids

Answer 3

pH greater than 7, a (arrhenius) base; pH lower than 7, a (arrhenius) acid.

btw if something is an arrhenius-acid/base, it also fits the bronsted-lowry classification and the lewis acid/base classification (in a certain sense), according to chem: the central sci book

Answer 4

a strong acid/base dissociates readily, and so their solutions contain ions (H+, conjugate acid/base). as a result, the solutions have higher conductivity (than plain water).

because they form ions in solutions, strong acids/bases are electrolytes, and good conductors apply to both (strong) acids and (strong) bases, so i would guess "both"

Answer 5

react with metals vigorously... (arrhenius) acids come to mind, e.g.

Ca + 2H^+ --> Ca^2+ + H2(g)

why acids? because they increase the H^+ conc, pushing the reaction (above) to the product side.

not sure about bases, and they don't dissociate (i am sorry about the mistake above). according to the Bronsted definition, bases accept protons, and as a result the OH^- conc increases. in any case, a strong base is still an electrolyte in the sense that it increases the conc of dissolved ions.

so i am going to guess: reacts with metals... acids only.

Answer 6

feel slippery... bases only, according to chem: the central sci.

Answer 7

1) Base
2)Base
3)Acid
4)Both, because they have ions
5)Acid.... while bases can react with metals it in not very vigorous
6)Base
7)Acid
