Generator Load Test The salt/water ratio in the load bucket

The generator uses salt water for load testing. The method involves using a ceramic cylinder (cement porcelain is also acceptable) and preparing it according to the water/salt ratio (35:0.5 kg). Three live wires are connected. three copper rods or copper plates (requiredly fixed on the insulation board), after the voltage and speed of the generator reach the rated value, slowly put the copper rod or copper plate into the salt water

(1) Nanomaterials have strong adsorption properties and can increase the adsorption area and use manganese dioxide nanorods as the cathode material of this battery, which can improve the efficiency of energy production. So the answer is: stronger adsorption capacity (or larger surface area);

(2) Depending on the total battery size Reaction: 5MnO2+2Ag+2NaCL=Na2Mn5O10+2AgCl. Metallic silver perd electrons, and the oxidation reaction that loses electrons occurs on the negative electrode of the primary battery, so the The reaction of the negative electrode is Ag+Cl--e-=AgCl↓, forming 1mol? Na2Mn5O10 consumes 2mol of metallic silver and transfers 2mol of electrons, so the answer is: Ag+Cl--e-=AgCl↓;2;

(3) From the reaction: MnO2+ C2O42-+4H+= Mn2++2CO2↑+2H2O, 2MnO4-+5C2O42-+16H+=2Mn2++10CO2↑+8H2O, the relationship formula is obtained: 5MnO2--5C2O42---2MnO4-, assuming the formula of mass n of manganese dioxide, then

5MnO2--5C2O42---2MnO4-

5 2

I.e.

Answer: The mass fraction of MnO2 in pyrolusite is 72.5%.
