Since Kw= [H⁺][OH⁻], and the concentration of both substances are the same, the equation is now Kw=[H⁺]²
So,
3.31x10⁻¹³ = [H⁺]²
Take the square root= 5.75x10⁻⁷
Then take the negative log to find the pH:
-log(5.75x10⁻⁷) = 6.25
Answer:
NH3
Explanation:
Which salt is least soluble at 90 degrees Celsius
Fe + 3NaBr → FeBr3 + 3Na
The Na is replaced by the Fe atom.
this way they can make sure that the experiment is correct.
