In a solution, when the concentrations of a weak acid and its conjugate base are equal: 1. the -log of the concentration of H+ and the -log of the Ka are equal.
<h3>What are Strong acid strong bases ?</h3>
Any acid that entirely ionises in solutions is considered a strong acid. When positioned, it emits the most hydrogen ions or protons.
- It is a substance with the capacity to take a proton out of an extremely weak acid. In water, they can also entirely separate into its ions. Examples include sodium hydroxide and potassium hydroxide (KOH) (NaOH)
<h3>What are weak acid and weak bases ?</h3>
Acids that don't entirely dissociate in solution are referred to as weak acids. In other words, any acid that is not a strong acid qualifies as a weak acid. The amount of dissociation determines how strong an acid is; the more dissociation, the stronger the acid.
- Weak bases are basic compounds that, when dissolved in solutions, do not entirely separate into their constituent ions.

Both atoms must be non-metals,
Both atoms must have an incomplete outer energy level / shell of electrons
Answer: It takes 5.89 s for the concentration of
to decrease by 88.0%.
Explanation:

As the units of rate constant is
, the kinetics must be second order.
Integrated rate law for second order kinetics is given by:

= initiaal concentration = 0.590 M
a= concentration left after time t = 


Thus it takes 5.89 seconds for the concentration of
to decrease by 88.0%.
Answer:
Oxygen supports combustion so a good method of testing for oxygen is to take a glowing splint and place it in a sample of gas, if it re-ignites the gas is oxygen. This is a simple but effective test for oxygen.
Explanation:
