Which of these species can accept a proton,
I count 4!
Explanation:
A Bronsted-Lowry base is any species that will increase the concentration of
So a Bronsted-Lowry base is by this definition a proton acceptor (from
Phosphate anion,
All of these examples I flagged will affect
See explanation.
Explanation:
Bronsted-Lowry definition for a base, is any substance that can accept a proton
Let us take a look on the options one by one.
a-
It is a Bronsted-Lowry base because it accepts proton according to the following reaction:
b-
It is not Broasted-Lowry base, since it is a cation and it cannot accept a proton. Two same charge ions will repel.
c-
It is not Broasted-Lowry base, since it is an alkane (saturated hydrocarbon) and it cannot accept a proton. Alkenes and alkynes could be considered as Broasted-Lowry bases.
d-
This is the phosphate, which is the conjugate base of hydrogen phosphate (
e-
It is the hypochlorite, which is the conjugate base of hypochlorous acid (
f-
Magnesium carbonate is a salt that is made from the magnesium ion (
