Answer:
A
Explanation:
In a galvanic cell, energy is produced by spontaneous chemical processes.
The cathode and anode of this cell will depend on the relative position of the two metals in the electrochemical series.
Aluminium is higher in the electrochemical series so aluminium will be the anode. Silver is lower in the electrochemical series so silver will be the cathode.
Recall that oxidation (electron loss) occurs at the anode while reduction (electron gain) occurs at the cathode.
Strong acid on combining with strong base will always give neutral solutions. Consider the following example for the same
HCl + NaOH ↔ NaCl + H2O
(strong (strong
acid) base)
In above case, the resultant solution is neutral in nature.
On other hand, weak acid will react with strong base to form salt and water. But the solution will be basic in nature. Also, strong acid will react with weak base to form salt and water. But the solution will be acidic in nature
