Predict whether or not a precipitate will form if BaCl2 reacts with Ca(NO3)2. If a precipitate will form, write its formula. Why wouldn't HCl be a good acid to use to determine the solubility of a silver precipitate in an ...
To second sample we add BaCl2 instead of HCl, but nothing happens. We acidified solution with 0.1 M diluted nitric acid - there is no change. Then we add AgNO3 and we get a white precipitate. FeCl3 do not show up any change.
Answer the following questions; (a) What is the colour of iron (III) chloride precipitate? (b) What is the colour of iron (III) nitrate solution? What is the heat of solution (qsoln) for the neutralization reaction between NH3 and HCl? A white precipitate forms when ...
reached, in preparing a solution of TiOCl2 and BaCl2 by dissolving in water which was ultrafiltered beforehand, in adding this solution to the concentrated solution of oxalic acid, in filtering, washing and drying the precipitate formed, and in suspending the latter in a small amount of water....
BaCl2 + Na2SO4 arrow BaSO4 + 2NaCl When hydrochloric acid reacts with sodium carbonate, what gas results? How many moles of sodium carbonate (Na2CO3) are required to precipitate the calcium ion from 698.4 mL of a 0.35 M CaCl2 solution? What is the molar ma...
a) MgSO4 b) BaCl2 c) CH2(OH)2-CH(OH)-CH2(OH) d) CH2O Is the compound CuI2 soluble or insoluble in water? Explain. Using solubility guidelines, predict whether each of the following compounds is soluble or insoluble in ...
What is the concentration of barium ions in a 0.750 M BaCl2 solution? What concentration of chloride ion is required to precipitate 99.9% of the lead ion from a solution with Pb^{2+} = 0.045 mol/L? For a 2.5 M solution of Mg(NO3)2, what is...
