Question

Which of the following is a common property or characteristic of an acid?

Answer 1

Slippery feel

Bitter taste

Increases the hydroxide ion concentration in solution

Reacts with active metals to produce hydrogen gas

Answer 2

can you eliminate any from this list?

Answer 3

slippery feel and bitter taste i think.

Answer 4

yep, those are base properties.

Answer 5

now, does introducing an acid into a solution increase the number of hydroxide ions? OH-?

Answer 6

to be honest i have no idea.

Answer 7

okay. acids increase the number of hydronium H3O+ ions in solution (some teachers like to just write H+ although thats incorrect since that won't exist in reality) and by increasing that concentration they lower the pH ( pH is just a logarithmic measure of hydronium ion concentration).

Answer 8

bases increase the hydroxide concentration.

also a metal and an acid react in this way:


metal + acid -> salt + hydrogen gas

Answer 9

thankyou so much!!!! also would you happen to know What is true of a strong acid?

It ionizes close to 100 percent in water.

It is a weak electrolyte.

It does not conduct electricity in solution.

It always has a high concentration.

Answer 10

the characteristic of a strong base or acid is that they dissociate completely (and contribute the H3O+ or OH- from every molecule introduced) while weak acids and bases only dissociate a bit.

Answer 11

im sorry but what would that make it

Answer 12

It always has a high concentration. - not true for anything

It does not conduct electricity in solution. - ions conduct electricity, are H3O+ or OH- ions?


It is a weak electrolyte. - false, read above

It ionizes close to 100 percent in water. - are H3O+ and OH- ions?
