Ok so I'm doing chemistry 1 at uni and have done my first practical. I haven't much background at all in chemistry as I have taken it as an elective for my BEng(elec). I am finding it rather confusing with so many words to remember and so many links to be made between those words to understand. Perhaps I'm a stupid ape?
Here are the questions and my answers:::
Potassium carbonate to zinc carbonate:
Mix together aqueous solutions of Potassium carbonate and Zinc Nitrate then filter out the precipitated Zinc carbonate.
Magnesium sulfate to magnesium hydroxide:
Mix together aqueous solutions of magnesium sulfate and sodium hydrixide. Magnesium hydroxide isolated by filtration.
Lead nitrate to sodium nitrate:
Mix aqueous solutions of lead nitrate and sodium chloride together then filter out the lead chloride and evaporate the water from the resultant filtrate to get a hydrated sodium nitrate.
Please I have no idea if these are right but these are the answers that make sense to me at the moment hence the best i can do at the moment so please give some feedback. Thankyou
