Calculate the amount of the substance, which is 196 g of potassium hydroxide. How many ions of each type will this portion of alkali contain?
Decision:
1) n (KOH) = 3.5 mol
2) Analysis of the formula for potassium hydroxide shows that n (K⁺) = n (KOH), and n (OH⁺) = n (KOH).
3) N (K⁺) = 1 * 3.5 = 3.5
4) N (OH -) = 3.5
Answer: 3.5 mol, 3.5 and 3.5 ions.
