Ba(OH)2 dissociates according to the equation below to yield Barium ions and hydroxide ions.
Ba(OH)2 = Ba²⁺ + 2 OH⁻
The concentration of Ba²⁺ is 1.0 ×10^-3 M
Thus that of OH⁻ ions will be 2× 1.0 ×10^-3 = 2.0 × 10^-3 M
Thus; the answer is 2.0 × 10^-3 M
It is bases on "Atomic number"
In short, Your Answer would be Option B
Hope this helps!
Exactly! Conserving electricity protects the world. Try to save electricity as much as possible.
Yes, an explanation/ theory for a phenomena in science is not something that is set in stone. If experiments are done that prove the current explanation is false and this is peer checked, then the explanation can absolutely be proven false.
