Answer:
<h2>pH = 4.44 </h2>
Explanation:
The pH of a substance can be found by using the formula
where [ H+ ] is the hydrogen ion concentration of the solution
From the question
[ H + ] = 3.60 × 10^-5 M
So the pH is
We have the final answer as
<h3>pH = 4.44 </h3>
Hope this helps you
The electrons are transferred from potassium to sulphur, in this reaction, potassium is being oxidised and sulphur is being reduced. Two potassium atoms each lose one electron forming K+ ions. Sulphur gains two electrons forming S2-/2- ions. The resultant formula will be: K2S, bonding in this compound is ionic.
Answer:
If NH4+ is removed, the reaction will shift toward products to replace the product removed. This means the reaction will shift to the right.
Explanation:
A solution of ammonia NH3(aq) can be written through the following equation:
NH₃(aq) + H₂O(l) ⇌ NH₄⁺(aq) + OH⁻(aq)
If the concentration of one of the reactants changes, the balance will shift in such a way that the change in concentration is counteracted.
If NH4+ is removed, now there is less product, so the reaction will shift toward products to replace the product removed. This means the reaction will shift to the right.
This principle is due to the fact that the equilibrium constant for this reaction is constant at a certain temperature. The ratio of reactants and products is fixed. Any change in concentration disrupts the balance and will result in the balance being restored.
Answer:
The ocean is made up of salt water, which is a combination of fresh water, plus minerals collectively called "salts." These salts aren't just sodium and chloride (the elements that make up our table salt), but other minerals such as calcium, magnesium, and potassium, among others.
Explanation:The answer is since particles can be found in ocean water It is a compound, since it results from the combination of elements It is a solution
