What are the concentrations of hydrogen ion and hydroxide ion in household ammonia, an aqueous solution of NH₃ that has a pH of 11.00?
Answer : The concentrations of hydrogen ion and hydroxide ion in household ammonia is,
and ![1.00\times 10^{-3}M](https://tex.z-dn.net/?f=1.00%5Ctimes%2010%5E%7B-3%7DM)
Explanation :
As we know that the aqueous solution of ammonia is ammonium hydroxide that is, ![NH_4OH](https://tex.z-dn.net/?f=NH_4OH)
The equilibrium reaction will be:
![NH_4OH\rightleftharpoons NH_4^++OH^-](https://tex.z-dn.net/?f=NH_4OH%5Crightleftharpoons%20NH_4%5E%2B%2BOH%5E-)
Given:
pH = 11.00
First we have to calculate the hydrogen ion concentration.
pH : It is defined as the negative logarithm of hydrogen ion concentration.
![pH=-\log [H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH%5E%2B%5D)
![11.00=-\log [H^+]](https://tex.z-dn.net/?f=11.00%3D-%5Clog%20%5BH%5E%2B%5D)
![[H^+]=1.00\times 10^{-11}M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D1.00%5Ctimes%2010%5E%7B-11%7DM)
Now we have to calculate the pOH.
![pH+pOH=14\\\\pOH=14-pH\\\\pOH=14-11.00\\\\pOH=3.00](https://tex.z-dn.net/?f=pH%2BpOH%3D14%5C%5C%5C%5CpOH%3D14-pH%5C%5C%5C%5CpOH%3D14-11.00%5C%5C%5C%5CpOH%3D3.00)
Now we have to calculate the hydroxide ion concentration.
![pOH=-\log [OH^-]](https://tex.z-dn.net/?f=pOH%3D-%5Clog%20%5BOH%5E-%5D)
![3.00=-\log [OH^-]](https://tex.z-dn.net/?f=3.00%3D-%5Clog%20%5BOH%5E-%5D)
![[OH^-]=1.00\times 10^{-3}M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D1.00%5Ctimes%2010%5E%7B-3%7DM)
Therefore, the concentrations of hydrogen ion and hydroxide ion in household ammonia is,
and ![1.00\times 10^{-3}M](https://tex.z-dn.net/?f=1.00%5Ctimes%2010%5E%7B-3%7DM)
Answer:
D: Carbon
Explanation:
The periodic table lists all the known elements. When looking at it, the only choice you will find is carbon. Therefore, carbon is the element.
Carbon is also by itself, just C.
Water is H2O, which is a molecule due to the 2 different elements.
Carbon Dioxide is CO2, which is a molecule due to the 2 different elements.
Air is just a mixture of different gas molecules, so therefore it is not an element.
<h3>What is the equilibrium constant?</h3>
The equilibrium constant shows the extent to which reactants are converted into products.
In this case, we must find the reaction quotient as follows;
Qc = [0.55]^2/[0.12] = 2.5
Since the Qc > Kc, it means that the reverse direction is favored in this reaction.
