Why does displacing copper using zinc produce a black precipitate? Precipitate: Precipitates are the solid insoluble products produced in certain reactions which are taking place in a solution. Such reactions are generally termed precipitation reactions. Sodium chloride is an example of a precipitate. ...
Does a precipitate form when copper(II) sulfate and sodium hydroxide are mixed? If so, write the empirical formula of the precipitate. Predict whether or not a precipitate will form if NaI reacts with AgNO3. If a precipitate will form, wr...
Why does CrO3 in acidic water oxidize? Why do copper (II) sulfate crystals not conduct electricity? Explain why the copper element has two ion charges. Why do metals conduct heat and electricity? Why does displacing copper using zinc produce a black precipitate?
The ubiquitous use of chromium and its derivatives as corrosion preventative compounds accelerated rapidly after the second industrial revolution, with such compounds now integral to modern society. However, the detrimental impact of chromium compounds o
Copper Sulfate 2 5 10 57 115 231 It is impractical to convert all of the water processed to product water for several reasons including the osmotic pressure which develops as a result of the concentration of the dissolved ions which accumulate on the one side of the membrane, and the inabili...
What might happen if a piece of zinc metal is placed in a solution of magnesium nitrate? Silver metal may be precipitated from a solution of silver nitrate by placing a copper strip into the solution. What mass of AgNO3 would you dissolve in water in order to get 1...
Explain the effect of the nitrate/sulfate/chloride ion when chemically combined with a metal on the color emission? Would you expect silver to dissolve in 1 M HCl? Justify your answer Explain the function of the aluminum wire and the mercury II chloride when ...
