<span>
You have OH- conc = </span>2.3 ✕ 10−6 m
From the formula, you can observe the ratio of Cu2+ to OH- is 4 : 6 = 2:3
So, for 2.3 ✕ 10−6 m OH-
[Cu2+] =

The radioactive decay of unstable isotopes continually generates new energy within Earth's crust and mantle, providing the primary source of the heat that drives mantle convection. Plate tectonics can be viewed as the surface expression of mantle convection.
Answer:
It becomes negative
Explanation:
protons carry a positive charge
neutrons carry a neutral charge
electrons carry a negative charge
if we add 2 more electrons, the charge of the ion becomes negative
