Answer is: H₂O → H⁺ + OH⁻.
Water dissociates (autoionization) to form hydrogen ions (H⁺) and hydroxide (OH⁻) ions. The protons (H⁺) hydrate as hydroxonium ions( H₃O⁺).
The Kw (the ionic product for water) at 25°C is 1·10⁻¹⁴ mol²/dm⁶ or 1·10⁻¹⁴ M². Concentration of hydrogen ions and hydroxide ions in pure water are the same.
When a strong acid and strong base are combined, it forms a neutral salt. Therefore, Na₂SO₄ is a neutral salt because it is the product of NaOH (a strong base) and H₂SO₄ (a strong acid).
Answer:
The answer is 54.2 seconds
Explanation:
If you divide 542 by 10 you get 54.2 which is then labeled as seconds.
Answer:
Explanation:
Hello,
In this case, we work on a dilution process in which we can state that the moles remain the same after the dilution process. In such a way, we can write:
That in terms of molarities and volumes is:
Whereas is the initial molarity (3.00 M) of the stock solution, the molarity of the diluted solution (0.289 M), the aliquot of the stock (concentrated) solution and the volume of the diluted solution (100 mL), thus, we compute as required:
Best regards.
