Answer: 5.48
Explanation:
pH is the negative logarithm of hydrogen ion concentration in a solution.
Mathematically, pH = - log(H+)
where H+ represent the concentration of hydrogen ion
So, to get the pH of the solution with [H +] = 3.25×10-6 M:
Apply, pH = -log(H+)
pH = - log (3.25×10-6 M)
pH = - ( -5.48)
(Note that the minus signs will cancel out each other)
Therefore pH = 5.48
Now we know that the pH of the solution with hydrogen ion concentration of 3.25×10-6 M is 5.48 (i.e slightly acidic)
Thus, we can finally say 5.48 is the pH of the solution within a solution with pH = 4.50

Answer:
The answer to your question is Ionic bonding. Magnesium loses 2 electrons and Chlorine gains 1 electron
Explanation:
An Ionic bond is formed between a metal and a nonmetal and the difference of electronegativity is higher than 1.7. In this type of bond, metals lose electrons and nonmetals gain them.
Covalent bonding is formed between two nonmetals and the difference of electronegativity is between 0 and 1.7. Elements share electrons.
Process
Electronegativity of Mg = 1.31
Electronegativity of Cl = 3.16
Difference = 3.16 - 1.31
= 1.85
1.85 > 1.7 then the bond formed is Ionic
Magnesium loses 2 electrons and Chlorine gains 1 electron
Alkali Metals (Group 1) elements experience an increase in the vigour of their reaction in water as they go down the group (as the atomic number increase). As such the most reactive Alkali Metal would be
FRANCIUM, which is at the base of Group One.
Quite frankly, you do not want Francium to react with water- that's a huge explosion on your hand.
