A caption is a positively charged ion. They are formed when an ion loses one or more electrons. Typical it is the loss Of their valence electrons.
c(desired)*V(final) = c(conc)*V(add)
V(add) = c(desired)*V(final) / c(conc) = 2*0.5 / 12 = 0.0833 cm3 = 83.3 mL of 12 M HCl needs to be added.
First add the distilled water: 416,7 mL.
Then add the conc. HCL by using an autopipette 8 times with 10.0 mL, 1 time with 3.0 mL and then 1 time with 300 microliter .
