Hbr Ca Oh 2
HBr (Blue) + Ca (OH) 2 (Blue)>? 3
I assume it's H20 + OH + CaBr.
Can you also tell me how you know which elements come together?
It is an acid (hydrobromic acid) and a base (calcium hydroxide) that always forms salt and water in a neutral reaction.
Salt is calcium bromide (calcium is in group 2, so the formula of calcium bromide is CaBr2)
So basically we have.
HBr + Ca (OH) 2> CaBr2 + H2O, but requires balance:
2HBr (blue) + Ca (OH) 2 (blue)> CaBr2 (blue) + 2H2O (l)
2 HBr + Ca (OH) 2 = CaBr2 + 2 H2O
Weak acids react with lime and saline water.
Acid base reaction.
Note that + and ions are glued together.
Hbr Ca Oh 2
Hbr Ca Oh 2
Acid + base = salt + water
2 HBr + Ca (OH) 2 = CaBr2 + 2 H2O
The correct answer to mastering chemistry is:
H + (aq) + OHÃ Â '(aq) Â'H2O (l)
