The correct answer is Option 3: 4
To determine the total number of ions produced from the compound [Cr(NH3)6]Cl3 in aqueous solution, we need to understand how it dissociates.
The compound [Cr(NH3)6]Cl3 is a coordination compound. When dissolved in water, it dissociates into its constituent ions:
[Cr(NH3)6]Cl3 (aq) → [Cr(NH3)6]3+ (aq) + 3Cl- (aq)
From the dissociation equation, we can see that it produces:
Therefore, the total number of ions produced is 1 + 3 = 4.
