Explanation:
Answer: You have a solution of potassium chlorate containing 4 g at 65º C. How many additional grams of solute must be added to it, to make the solution saturated ? approximately 26 more grams [the solubility of potassium chlorate is ... water. The solution is allowed to cool. At what new temperature would crystals begin to.
Explanation:
Answer:
Hydroxyl ion concentration is 
.
Explanation:
From the given,
pH of the solution = 11.30
pH+pOH = 14
11.30 + pOH = 14
pOH = 14-11.30 = 2.7
The pOH of the solution is 2.7
<u>Concentration of hydroxyl ion:</u>
![2.7= -log[OH^{-}]](https://tex.z-dn.net/?f=2.7%3D%20-log%5BOH%5E%7B-%7D%5D)
![log[OH^{-}]= -2.7=5.08\times10^{-11}M](https://tex.z-dn.net/?f=log%5BOH%5E%7B-%7D%5D%3D%20-2.7%3D5.08%5Ctimes10%5E%7B-11%7DM)
Therefore, hydroxylion concentration is .
