Question

which of the following is the correct Arrhenius definition of an acid?

Answer 1

A substance that dissociates in water to produce hydrogen ions (H+)

Answer 2

A) an acid is a proton donor
B) An acid is a substance that produces H+ ions in water
C) An acid is a substance that produces hydroxide ions in water
D) AN ACID is a substace that is sour to the taste

Answer 3

i can pick more that one if apply

Answer 4

so is it C

Answer 5

No, hydroxide is OH- not H+

Answer 6

it is B THEN

Answer 7

RIGHT

Answer 8

Yes, that is one of them. :)

Answer 9

A H+ is also commonly referred to as a proton.

Answer 10

there are more than one answer

Answer 11

Yes.

Answer 12

its a and b

Answer 13

right

Answer 14

Yup :)

Answer 15

@toxicsugar22 You always demand an answer, and never take time to learn the material. Do not ask me to you "help" you if this is what you will be doing. I hardly think giving you an answer is "helping" you or benefiting you in anyway.

Answer 16

a strong acid is an acid that is completly ___________ in aqueous solution

is it completely ionized.

help me fill in the blank

Answer 17

Yes, a strong acid completely ionizes in water. :) Good job!

Answer 18

nice name. i think all correct. I need to know what Arrhenius means. I assume it's the layperson's definition and therefore my option would be D. Additionally seriously the other choices are not exclusive to acids. Again I would choose D.

what does Arrhenius mean?

Answer 19

he Arrhenius definition of acids and bases is that An Arrhenius acid is a substance that when added to water increases the concentration of H1+ ions present. The chemical formulas of Arrhenius acids are written with the acidic hydrogens first. An Arrhenius base is a substance that when added to water increases the concentration of OH1- ions present. HCl is an example of an Arrhenius acid and NaOH is an example of an Arrhenius base.

Answer 20

yes it is a nice name

Answer 21

am i correct Joanna

Answer 22

acids have positive charge (base negative)

Answer 23

Arrhenius defined acids as substances that contribute H+ ions when dissociated in water, and bases as those that contribute OH- ions when dissociated in water. Bronsted & Lowry had a separate definition for an acid but same premise.

Answer 24

Yes, you are correct, @toxicsugar22

Answer 25

after reading the definition
the correct Arrhenius definition of an acid is substance that contribute H+ ions when dissociated in water choice b

Answer 26

by the way thanks for the definition
