Question

Which equation shows the reaction between a weak acid and a strong base?


HC2H3O2 (aq) + OH− (aq) arrow C2H3O2− (aq) + H2O (l)

3H+ (aq) + Al(OH)3 (s) arrow Al+3 (aq) + 3H2O (l)

Na+ (aq) + Cl− (aq) arrow NaCl (aq)

HI (aq) + NaOH (aq) arrow NaI (aq) + H2O (l)

Answer 1

Which one do you think it is?

Answer 2

I think it is C. but I'm not sure because I keep getting something from D too. @taramgrant0543664

Answer 3

I think it is A

Answer 4

actually

Answer 5

Which is the correct net ionic equation for the following reaction: 2HI (aq) + Ca (OH)2 (aq) arrow CaI2 (aq) + H2O (l)?


H+ (aq) + Ca+2 (aq) + 2 I− (aq) arrow CaI2 (aq)

Ca+2 (aq) + 2 OH− (aq) arrow Ca(OH)2 (aq)

H+ (aq) + OH− (aq) arrow H2O (l)

2HI (aq) + Ca (OH)2 (aq) arrow CaI2 (aq) + H2O (l)
do u mind helping me out with this one real quick

Answer 6

Yes it is A the weak acid is a condensed form of acetic acid and OH- is a strong base

Answer 7

do u mind helping me with the second question ? @taramgrant0543664

Answer 8

Yep just give me a sec

Answer 9

aight @taramgrant0543664

Answer 10

Full ionic equation is:
Ca2+(aq) + 2OH- (aq) + 2H+(aq) + 2I- (aq) → Ca2+(aq) + 2I-(aq) + 2H2O(l)
Therefore Net Ionic equation is:
2OH- (aq) + 2H+(aq) → 2H2O (l)
Simplifying you should get:
OH - (aq) + H+(aq) → H2O(l)
