Do not enter units as part of your answer 5. Calculate [OH-] for a 0.129 M HCIO44 solution. Use significant figures and "E" for scientific notation. Do not enter units as part of your answer.Explanation / Answer
1.
H2CO3 can donate two protons. Subtance that can donate two protons is called diprotic acid.
A diprotic acid can donates two protons.
A binary acid is the one which is formed by combination of H and non-metal and has general formula HX.
An amphiprotic molecules means it can donate proton as well accets proton.
Bronsted-Lowry base is the one which accepts protons.
So, the best discription of the image is A) A diprotic acid.
