The conjugate acid of CNO- is
a. HCNO
b. CNO-
c. CN-
d. H2CNO
e. HCN
Not quite sure for this question, is A the answer?
Need help, thanks.
yes
Thanks!
To determine the conjugate acid of CNO-, you need to identify the species that would gain a proton, H+, to become its conjugate acid.
The formula for CNO- is cyanate ion. To obtain the conjugate acid, H+ needs to be added.
The correct answer would be e. HCN. Adding a proton to CNO- will result in the formation of HCN, which is the conjugate acid. Therefore, option e, HCN, is the correct answer.
To identify the conjugate acid of a given species, you need to understand acid-base reactions and the concepts of conjugate acid/base pairs.
An acid is a species that donates a proton (H+), while a base is a species that accepts a proton.
The conjugate acid of a base is formed when the base accepts a proton, and conversely, the conjugate base of an acid is formed when the acid donates a proton.
In this case, the species given is CNO-, which is a base as it can accept a proton. To identify its conjugate acid, we need to determine which species will donate a proton to CNO-.
Out of the options provided, option (a) HCNO can donate a proton to CNO-, thereby forming its conjugate acid.
Therefore, the correct answer is a. HCNO.
