b) Una solución en que [H+] = 1.0x10-6 M
c) Una solución en que [H+] = 1.0x10-8 M

Each mineral has its own properties different from other minerals because minerals are made up of different elements. Different elements which can be found on the periodic table all have unique properties, therefore, gold will have distinct properties in comparison with zinc or aluminum for example because they are made up of different elements :
