Question

Which of the following is a common property or characteristic of a base?

Sour taste
Corrosive to skin, clothing, and other substances
Increases the hydrogen ion concentration of a solution
Slippery feel

Answer 1

what you say...?

Answer 2

well i looked up the characteristics of bases and it said
Taste bitter.
2) Turn red litmus paper blue.
3) Don't react with metals.
4) Feel slippery.
5) Contain hydroxide ion or produce it in a solution.

Answer 3

Look at 4)

Answer 4

so silppery feel ??

Answer 5

i will say sour taste...

Answer 6

hmm why?

Answer 7

Soap is basic and it's slippery

Answer 8

none of these properties are common to all bases. The term ALKALI is more appropriate. Bases include enumerous class of organic derivatives also all of which may not be slippery and sour. All may not be corrosive too. As for alkalis - Sour taste is common.

Answer 9

ahh idk what to choose :/

Answer 10

That's a main characteristic of an acid is sour taste. Bases taste bitter. Compare lemon juice (acid) and soap (base).

Answer 11

hmm no

Answer 12

Definition of acid (n)

Bing Dictionary
ac·id
[ ássid ]


1.corrosive substance: a sour-tasting compound that releases hydrogen ions to form a solution with a pH of less than 7, reacts with a base to form a salt, and turns blue litmus red.
2.compound forming covalent bond with base: a compound that can donate a proton or accept a pair of electrons to form a covalent bond with a base

Answer 13

tell me, what is alkali...?

Answer 14

it says sour tasting ?!?!?

Answer 15

All alkalis react with ""acids"" to form a salt and water......

Answer 16

Base definition

In chemistry, a base is a substance that, in aqueous solution, is slippery to the touch, tastes bitter, changes the color of indicators, reacts with acids to form salts, and promotes certain chemical reactions. Examples of bases are the hydroxides of the alkali and alkaline earth metals. Such substances produce hydroxide ions in aqueous solutions, and are thus classified as Arrhenius bases. For a substance to be classified as an Arrhenius base, it must produce hydroxide ions in solution—in order to do so, Arrhenius believed the base must contain hydroxide in the formula.

Answer 18

sorry no extra time with me... i will say "Sour taste" is rite.... :) @superhelp101

Answer 19

okay :) idk but when i get the correct answer i will let you guy know!!

Answer 20

sure... now close this question....

Answer 21

Well @superhelp101 you know that the 1st and 2nd choices are both for acids and bases actually increase the hydroxide ion concentration of a solution, but personally I think it's the 4th because all bases are slippery

Answer 22

okay thanks

Answer 23

No prob :)
