The answer is Conduction. I hope this helps!
In an acidic solution, the concentration of H+ is greater than the concentration of OH-. The pH will be less than 7.
In a basic solution, the concentration of OH- is greater than the concentration of H+. The pH will be greater than 7.
In a neutral solution, the concentration of H+ ions to OH-ions will be equal, and will therefore have a pH of 7. (This is due to water autoionization, which we usually ignore because it is small in other circumstances.)
Answer:
Ca
Explanation:
Calcium atom has two electrons that are loosely attached to its outermost energy level. It easily looses these electrons during reactions than the other three elements ( aluminium,sodium and oxygen).
Ca₍aq₎⇒ Ca²⁺₍aq₎+2e⁻
Calcium ionizes by losing 2 electrons from its outer shell to form an ion with a charge of 2+
