1. What are the recognised solubility rules? I keep getting different exceptions from different sources. 2. What is the least amount of ionic compound which needs to be dissolved in water to make that compound soluble? 3. What are the boundaries between insoluble, slightly soluble and...

How much detail do we have to know for "- outline the use of highly variable genes for DNA fingerprinting of forensic samples, for paternity testing and for determining the pedigree of animals" In some textbooks (Jacaranda) there is an insane amount, while in the Heinemann it seems to...

ok then tks

What are the consequences of not telling the truth?

Can someone tell me the wheter each of the following substance is acidic/basic and its parent acid and bases please. -ammonium chloride (NH4Cl) -copper sulfate (CuSO4) -Potassium Thiocyanate (KSCN) -Potassium Chloride (KCl) thank you

oic now tks

Really i hope so lol, but if we do have to remember the ions test, do we need to know the solubility rules and the colour of the precipitates tests?

You know the dotpoint "deduce the ions present..." do we just remember a flowchart for that?

mhmm thanks for that Tennile.

Re:  discuss, using a recent example, how progress in analytical chemistry and chang mmm can't seem to find any queswtions.

thanks a lot.

Is my dotopoint ok?doi need to add/take away anything? "The advancement and changes in analytical technology have teh ability to affect the outcomes of forensic investigations. This was clearly observed in the Azaria Chamberlain case of the 1980s and 1990s. On August 17, 1980...

I was just wondering if there were anyother books, but CC4 is too expensive. i guess i'll stick with CC3 then. Alrighty thanks.

Does it contain EVERYTHING we need to know, so that if I just remember the whole chapter I can score high marks in an exam?

Do wehave to know about greenhouse and NOx effects?

How do you do this question: "Q. A paper mill produces waste water which contains 0.20M NaOH. What volume of HCl solution with a pH of 1 would be needed to bring 5000L to a pH of 7?" THankyou!

ok, well thanks anyway

Why is adding acid increasing acid while addin base is decreasing acid?

-perform a first-hand investigation to determine the concentration of a domestic acidic substance using computer-based technologies? thks

Here's teh example HA + H2O <--> H3O+ + A- -- If an acid is added, the hydronium ions react with A- therefore equilibrium shifts to the right to replace A- --If a base is added, the hydroxide ions react with H3O+ and thus equilibrium shifts to right to replace the H3O+...
