pH of the Sr(OH)₂ solution : 12.6
<h3>Further explanation </h3>
pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.
pH = - log [H⁺]
Sr (OH) ₂ solution is a base with valence 2, so we determine the pOH from the OH ion concentration - which is expressed by pOH = - log [OH -]. After that we determine the pH value from the relationship:
[H⁺] [OH⁻] = Kw=10⁻¹⁴
pH + pOH = 14
Sr(OH)₂⇒Sr²⁺+2OH⁻
From equation [Sr(OH)₂] : [OH⁻]=1 : 2, so [OH⁻]=
Answer:8.933572
Explanation:
for an approximate result, multiply the volume value by 3.785
It would be 5 ML of chloride dissovled
Answer:
The answer is B
Explanation:
In an exergonic process, what happens is that energy is released in the form of heat, light, etc. They are spontaneous processes.
It can be said that after an exergonic reaction there is less energy than before the reaction, it is expressed as follows: ΔG < 0
ΔG (Gibbs Free Energy)
