Barium reverses so it's soluble
Also it's a common base

correct

Uranium phosphate

awwww shiiiiiit LOL... eenie meenie minie mo......

Insoluble?

lol

 

[axlenatore]

correct

lol

In truth i dont know, i just wanted to ask something from left field,

does Uranium Phosphate even exist?

Ferric Hydroxide

 

[JasonNg1025]

Yah I'm guessing insoluble
Majority of phosphates are, and uranium is heavy

 

[danz90]

hey guys..

how do we differentiate between purifying and sanitising water?

Ferric Hydroxide

In truth im not sure

 

[JasonNg1025]

Ferric hydroxide insoluble?

Purifying is making clear of impurities such as ions dissolved and undissolved solids and all that. Sanitising I think is making it clear of microorganisms?

 

[aussiechick007]

all hydroxides and oxides are insoluble.......... if i rmemeber right!

ammonium nitrate

 

[axlenatore]

ammonium nitrate

soluble

copper carbonate

 

[danz90]

Ferric Hydroxide is insoluble, Jason's right.

I started laughing when I saw a glass container labelled Fe(OH)₃ in one of the prep-rooms at school, with a brown-orange liquid in it, which had no solid, was all liquid. lol dumb lab assistant.

Ammonium nitrate is soluble, as all nitrates are soluble.

 

[JasonNg1025]

Insoluble to copper carbonate

Copper Chloride

 

[danz90]

soluble

copper carbonate

insoluble

 

[danz90]

Insoluble to copper carbonate

Copper Chloride

Soluble

Magnesium Acetate

 

[JasonNg1025]

Soluble

Ammonium Molybdate

 

[danz90]

Soluble

Ammonium Molybdate

Gosh I've never heard of that.

Ohhh.. actually I remember you said thats used to precipitate phosphate ions. So hence it must be soluble ?

 

[JasonNg1025]

Yes xD
And priorities - no matter how bad molybdate is, ammonium and Group 1 ions always out prioritise it, so it must be soluble
So what's next

 

[danz90]

I'm off for a few minutes to go call the advice line before it closes.
Be back soon

 

[Undermyskin]

I suppose 'purify' includes 'sanitize' and 'filter'.

 

[JasonNg1025]

Yes, I'd say that was correct.
But when they ask you to purify and sanitise, include chloronation and fluoronation for the sheer heck of it.

I'm pretty happy with what the advice line said about my questions

-Firstly I asked about the dotpoint on a chemist in named industry. You don't actually have to know the name of a chemist - but rather concentrate on the industry they are employed in, their role, and what chemical principles they use.

-The equation that I've given in one of the threads in Production of materials subforum in regards to reduction in the Dry Cell is correct - Mn₂O₃ reacts with water in the electrolyte paste to produce Manganese(III) Hydroxide anyway. happy that I clarified that, I panicked a little.

- And for the dotpoint that asks us to asses evidence of increasing concentrations of acidic oxides in the atmosphere - the point that air pockets ice shafts in antarctica are analysed to show historical trends is good to mention, coz u can question its accuracy - apparently Sulfur Dioxide and Nitric Oxide would would dissolve in the water in the ice-cap anyway, and wouldn't be trapped as a gas in an air pocket.

The advice line is awesome, pity this is the last year they doing it.
