Question

write molecular, complete ionic, and net ionic equations for the reactions that occur, if any, when solutions of the following substances are mixed: acetic acid and calcium hydroxide

Answer 1

@oOKawaiiOo

Answer 2

i just need the molecualr equation and from there i can continue

Answer 3

HC2H3O2 + ClOH ===> ???

Answer 4

OR CH3COOH + ClOH ===> ???

Answer 5

Ca is calcium
Cl is chlorine
CH_3COOH is acetic acid

Answer 6

YES SO ...

Answer 7

did not mean to write caps

Answer 8

@UnkleRhaukus

Answer 9

so what is ClOH ?

chlorine hydroxide? impossible

Answer 10

i meant CaOH

Answer 11

yes

Answer 12

ok and then ?

Answer 13

so
\[CH_3COOH + CaOH \rightarrow\]

Answer 14

equals what

Answer 15

i do not what to equal it to

Answer 16

2CH3COOH (aq) + Ca(OH)2 (s) ---> Ca(CH3COO)2 (aq) + 2H2O (l)
2CH3COOH- (aq) + 2H+ (aq) + Ca(OH)2 (s) ---> Ca2+ (aq) + 2 CH3COO- (aq) + 2H2O (l)
cancel out spectator ions
2H+ (aq) + Ca(OH)2 (s) ---> Ca2+ (aq) + 2 H2O (l)

Answer 17

thanku so much :)

Answer 18

np, sorry it took a while to type lol

Answer 19

can u plz help me with one more

Answer 20

sure go for it

Answer 21

2CH3COOH (aq) + Ca(OH)2 (s) ---> Ca(CH3COO)2 (aq) + 2H2O (l)
2CH3COOH- (aq) + 2H+ (aq) + Ca(OH)2 (s) ---> Ca2+ (aq) + 2 CH3COO- (aq) + 2H2O (l)


how did u know ehich type of equaiton is this @Sheng
cancel out spectator ions
2H+ (aq) + Ca(OH)2 (s) ---> Ca2+ (aq) + 2 H2O (l)

Answer 22

which*

Answer 23

i knew the type of reaction it was going to be because it's an acid + base reaction
acetic acid (acid) + calcium hydroxide (base) will always produce a salt (calcium acetate) and water

Answer 24

so if it is not of the strong bases and acids that i memorized, how would i know that is a base and that is an acid

Answer 25

well acetic acid has the word acid in it lol, and all hydroxide compounds are bases because OH- is a very basic substance

Answer 26

oh ok then thanku again for ur assistance

Answer 27

no problem!

Answer 28

sorry if i keep asking u too many questions but just one more @Sheng

Answer 29

why did u put +2H+

in the following

2CH3COOH- (aq) + 2H+ (aq) + Ca(OH)2 (s) ---> Ca2+ (aq) + 2 CH3COO- (aq) + 2H2O (l)

Answer 30

@Sheng

Answer 31

because CH3COOH deionizes in solution to CH3COO- and H+
but since there were 2 CH3COOH, i had to put 2H+ for correctness in balancing

Answer 32

but u have it on the left side not the right side

Answer 33

because it went into the water molecule, which doesnt deionize it itself

Answer 34

no i mean is not it supposed to be

2CH3COOH- (aq) + Ca(OH)2 (s) ---> 2H + Ca2+ (aq) + 2 CH3COO- (aq) + 2H2O (l)

Answer 35

2H+ actually

Answer 36

oh wait ok now i get it

it id part of the water molecule

sorry

Answer 37

no because if something is aq, you must write it as deionized, which is why you needed the 2H+ and CH3COO- on the left side. However on the right side it's not needed because the the 2H+ originally on the left side combined with OH- in Ca(OH)2 (s) formed water which is a liquid

Answer 38

np, net ionic equation was very confusing to me also at first, just keep working at it and it'll become more obvious :)
