Answer:
The components present in the solution are:
CH₃NH₂
CH₃NH₃⁺
NO₃⁻
Explanation:
CH₃NH₂(aq) + HNO₃(aq) → CH₃NH₃⁺ NO₃⁻
t = 0,
milliequivalent
100*0.25 = <em>25</em> 50*0.25 = <em>12.5</em>
End of reaction:
25 - 12.5 = <em>12.5</em>, 12.5 - 12.5 = <em>0</em>, 25 - 12.5 = <em>12.5</em>
<em />
moles of CH₃NH₂ left = 12.5x10⁻³ = 0.0125 > 0.001
moles of HNO₃ left = 0
moles of CH₃NH₃⁺ left = 12.5x10⁻³ = 0.0125 > 0.001
moles of NO₃⁻ left = 12.5x10⁻³ = 0.0125 > 0.001
Therefore, the component present in the solution are: CH₃NH₂ , CH₃NH₃⁺ , NO₃⁻
