Answer: The answers are the first and third options.
Hello!
This question can be solved using the
Henderson-Hasselbach equation, but first we need to know the value of pKa
pKa= -log(Ka)= -log(7,1*10⁻⁶)=5,15
Now, we apply the equation:
So, the pH of this solution would be
4,98
Have a nice day!
Substances can change state, usually when they are heated or cooled. For example, liquid water turns into steam when it is heated enough, and it turns into ice when it is cooled enough. ... The closeness, arrangement and motion of the particles in a substance change when it changes state.
The primary condition for a reaction to reach dynamic equilibrium is that "rate of forward reaction must be equal to the rate of reverse reaction." Furthermore, in a state of dynamic equilibrium, it has a unique synthesis wherein reactants are converted to products and vice versa.
