Anode
According to the mnemonic “Red Cat An Ox”, oxidation occurs at the anode and reduction occurs at the cathode. Since the reaction at the anode is the source of electrons for the current, the anode is the negative terminal for the galvanic cell.
The correct name for the hydrate salt is calculated as follows
calculate the mass of water =mass of hydrated salt- mass of anhydrous salt
4.56-2.92=1.64g
mass of anhydrous salt (CuSo4)= 2.92g
calculate the mole of water and anhydrous salt
that is
moles =mass/molar mass
moles of water = 1.64g/18g/mol= 0.0911 moles
moles of CUSO4 =2.92g/ 159.5 g/mol=0.0183 moles
find the moles ratio by dividing with the smallest moles that is 0.0183 moles
for H20 = 0.0911/0.0183= 5
CuSO4 = 0.0183/0.0183=1
the formula hydrate salt = CuSO4.5H20 which is known as copper (ii) sulfate pentahydrate
It is a. oxidation-reduction
reference refers to something that is not moving with respect to an observer that can be used to detect motion. But if they use objects outside the bus as their frame of reference, they can tell they are moving.
