Answer 1

@gsoda @AravindG @Azteck @nubeer @ganeshie8

Answer 2

@UnkleRhaukus @him1618 @radar

Answer 3

a strong acid/base completely ionises, look at the chemical structure

Answer 4

take eg. acetic acid and hydrochloric acid!!!

\[acetic \space acid=CH_3COOH \space and \space hydrochloric \space acid =HCl\]

Answer 5

i know acetic acid is weak and hydrochloric acid is strong!!
but how can i prove it???

Answer 6

first,i just think use a pH meter.
second, looking at its chemical formula.

Answer 7

@Machida neglect pH scale....use chemical formula

Answer 8

nah, then looking at chemical formula.

Answer 9

yaa!!! please can you show me???

Answer 10

Strong acid must be halogen bonding with hydrogen.

Answer 11

@.Sam.

Answer 12

machida m in class 10...please show your work according to class 10

Answer 13

3.use Bronsted-Lowry theory.
Strong acids are 100% ionized acid in solvent.

Answer 14

lol dev, here im not use English on chem xD

Answer 15

can you show your work through chemical eq.

Answer 16

how can we prove that HCl is strong acid??? @Machida

Answer 17

@thomaster

Answer 18

\[HCl\] is a strong acid.
use Bronsted-Lowry theory.

Answer 19

**All organic acids are weak acids....
**and the strong acids are usually halogens bonded to a hydrogen like @Machida said...

Answer 20

@mayankdevnani you know Bronsted-Lowry formula?

Answer 21

no!!! i heard it first time!!

Answer 22

oh i forgot that you're in 10.
sorry, :D

Answer 23

but in my book....it is given that
\[\Huge HCl(l)-^{water}->H^+(aq)+Cl^-(aq)\]

Answer 24

so how can i know that it is a strong acid?? @Machida and @kausarsalley

Answer 25

a strong acid fully dissociates into its ions like shown above ...
a weak acid does NOT fully dissociate into its ions....
