Question
I can't understand that what wrong with this answer
Please give complete answer with explanation.
![When the
Hg²+ concentration is
2.91 x 104 M, the observed cell potential at
298 K for an electrochemical cell with the following reaction is
2.409V. What is the
Al+ concentration?
3H3²+ (aq) + 2AI(s) → 3Hg(1) + 2AI³* (aq)
[ar* ]
M
[ A**]²
[2.91×10-4]³
=4. 56 × 1010
2
[Al+3]=4. 56 × 1010 × [2. 91 × 10-]
=4. 56 × 1010 × 2. 464 × 10-11
=1. 1236
[Al+3]=V1. 1236
=1.06 M
Therefore,
the concentration of Al+3| is 1.06 molars](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb587a1b5-36b4-4a32-a743-edf570a5b30b%2F1f6d5ec9-3980-4afb-9160-fbdc098888f3%2Fqslz7d_processed.jpeg&w=3840&q=75)
