Answer : The ions present in the solution of
are
and
in aqueous state.
Explanation :
When
is in aqueous solution then they dissociates into their ions.
The reaction in aqueous medium is,

The charge on potassium ion is +1 and on carbonate ion is -2. To neutralize the charge on carbonate ion, two potassium ion must be used.
Therefore, the ions present in solution of
are
and [tex]CO^{2-}_3[tex] in aqueous state.
Answer:
0.001 M
Explanation:
The pH scale is used to determine the acidity or basicity of a solution.
- If pH < 7, the solution is acid.
- If pH = 7, the solution is neutral.
- If pH > 7, the solution is basic.
The pH is related to the concentration of hydrogen ions through the following expression.
pH = -log [H⁺]
[H⁺] = antilog -pH = antilog - 3 = 0.001 M
Answer:
the average weight of a frog is 0.8 ounces, so your answer would be 4
