Answer:
83.99 KC1 1.
Explanation:
What is the total number of grams of KCl (formula 2.200M=xmol - 200 mdr o mass = 74.6) in 1.00 liter of 0.200 molar solution? 3941+355 74.69 ml atonal 1.13 mol 174.6g) = 83.99 KC1 1.
If the hydrogen ion concentration of a solution is 10–10M, is the solution is definitely alkaline. The thing I used to determine that fact is a basic point - pH above 7 is always alkaline, and as a proof, we can see from the task that the concentration of hydroxyl OH- is pretty higher than hydrogen H+, which is a direct characteristic of the alkain solution.Here is a tip for you, I bet it will be useful : >7 = basic <7 = acidic 7 = neutral
