Question

4. Ступінь електролітичної дисоціації електроліту становить 0,15. Обчисліть, скільки з 500 формульних одиниць цього електроліту розпались на йони. ПОМОГИТЕ ПОЖАЛУЙСТА ДАЮ 20 БАЛОВ!!!!​

Answer 1

Ответ:

75

Объяснение:

Степень диссоциации 0,15. Значит, число формульных единиц, распавшихся на ионы равно 500*0,15 = 75

Answer 2

To calculate the number of ions produced by the electrolytic dissociation of an electrolyte, we need to know the degree of electrolytic dissociation and the number of formula units of the electrolyte. In this case, the degree of electrolytic dissociation is given as 0.15, and we have 500 formula units of the electrolyte.

To calculate the number of ions produced, we can use the following formula:

Number of ions = Degree of dissociation * Number of formula units

Substituting the given values:

Number of ions = 0.15 * 500

Calculating this:

Number of ions = 75

Therefore, 75 ions are produced when 500 formula units of this electrolyte undergo electrolytic dissociation.

Please note that the degree of electrolytic dissociation is a measure of the extent to which an electrolyte dissociates into ions in a solution. It is usually expressed as a fraction or a decimal between 0 and 1. In this case, a degree of 0.15 means that only 15% of the electrolyte molecules dissociate into ions.

I hope this helps! Let me know if you have any further questions.
