What is this chemical equation?
the titration of Sr(OH)2 by HCl...what is that balanced equation?
Answer:
Sr(OH)2 + 2 HCl → 2 H2O + SrCl2
Strontium: 1 → 1
Oxygen: 2 → 2
Hydrogen: 4 → 4
Chlorine: 2 → 2
(Law of Conservation of Mass).
In other words, you can't have atoms coming out of no where or just disappearing.
Sr(OH)2 + 2HCl yields SrCl2 + 2H2O
is that what you meant?
That IS balanced by the way.
This is a typical reaction of a base and an acid in an aqueous solution (primary basis and consideration).
This is a double displacement reaction.
The positively and negatively charged ions are interchanged.
Think of it as two pairs of dancers exchanging partners.
Given the following ions:
Sr = +2
OH = -1
H = +1
Cl = -1
Note: Sr ions have the highest valence of 2 when compared to the rest of the other three ions. You could get an indication that the rest of these three ions must be multiplied by 2.
Equation:
Original reaction:
Sr(OH)2 + HCl = SrCl + H(OH)
Balanced Equation:
Sr(OH)2 + 2HCl = SrCl2 + 2H(OH)
Good Luck!
Hint:
You should memorize the valences of the elements as well as the radicals.
This is easier to do rather than knowing the orbital theory and then configuring the distribution of the electrons in the outer shell at its excited stages.
