Question

Why does it conduct more before and after this minimum point?

 
 

 

A chemistry student carried out an experiment with a conducting apparatus (ammeter) similar to the one below. This ammeter measures in milliamperes (mA). The following data was taken. Ammeter 6-12 volts Switch -Carbon Electrodes Test Solution Conductivity Apparatus Solution Reading 0.1 М Н2SO4 150 mA О.1 М Ba(ОН)2 | 150 mA To 30 mL of the Ba(OH)2 solution, 10 mL portions of H2SO4 were added until a total of 50 mL of H2SO4 were used. The following results were recorded.
