Answer:
Explanation:
When carbon dioxide dissolves and reacts with water, the water and the gaseous reacts to form a dilute mixture solution of
(carbonic acid ).
The reaction is
This is a forward reaction. And the symbol shows that the reaction can be reversible. It means that the reaction can be carried in forward direction as well as in the backward direction.
The reaction attains chemical equilibrium until the reactants and the products no longer changes with time.
The carbonic acid can also dissociates into carbon dioxide and water in the backward direction.
Answer:
Explanation:
Hello there!
In this case, since this concentration of hydronium ions is given, we infer we may calculate that of the hydroxide ions, pH and pOH because no question was specifically given. That is why we proceed as follows:
- pH: Here, we use this concentration to calculate the pH according to the negative logarithm:
Which means that the solution is acidic as the pH is less than 7.
- pOH: since the pH added to the pOH is 14, we can calculate the latter as follows:
- Hydroxide concentration: Given the pOH, we apply the antilogarithm to calculate such concentration as shown below:
Keep in mind, this is an arbitrary solution because no question was provided.
