Chemical Equation
« on: February 06, 2011, 06:33:34 pm »

How do I write the chemical equation for the reaction that takes place when aqueous Barium Hydroxide reacts with iron(III)chloride?
Is this an acid-base reaction? If so, what type?
How do i know if a substance is a base or an acid? i.e. is there any defining point which tells me a substance is willing to accept or donate protons?

Thanks.

2FeCl3 + 3Ba(OH)2 --> 2Fe(OH)3 + 3BaCl2

Its not acid-base, its a precipitation reaction (Fe(OH)3 is the precipitate)

Did you use the solubility table when you did that?

The rules, or the actual table?

Oh, I was referring to "all nitrates, ammonium compounds and compounds of group 1 metals are soluble" rule
how long did it take you to memorise the solubility table..i wish vcaa would include it in the data-booklet to eliminate the rote learn factor..

Nacho, you could do so many exercises that it eventually becomes second nature to you? ;x

Generally, your intuition would be right LoL

About Philosophy

When I see a youth thus engaged,—the study appears to me to be in character, and becoming a man of liberal education, and him who neglects philosophy I regard as an inferior man, who will never aspire to anything great or noble. But if I see him continuing the study in later life, and not leaving off, I should like to beat him - Callicle

Why would you memorise the solubility table when they give you it in the data book!?

Chem students at MHS are told to memorise solubilities and valencies; most have valencies memorised by the end of year 10.

I still haven't memorised mine. I'm a bad student :P
