What is the mass of potassium chloride when 6.75 g of potassium reacts with an excess of chlorine gas?
Balanced equation and potassium limits and drives the reaction.2K + Cl2 -> 2KCl6.75 grams K (1 mole K/39.10 grams)(2 mole KCl/2 mole K)(74.55 grams /1 mole KCl)= 12.9 grams potassium chloride produced==============================
Why is back titration required in the volhard method?
This method uses a back titration with potassium thiocyanate to determine the concentration of chloride ions in a solution.Before the titration an excess volume of a standardized silver nitrate solution is added to the solution containing chloride ions, forming a precipitate of silver chloride (AgCl). The term 'excess' is used as the moles of silver nitrate added are known to exceed the moles of sodium chloride present in the sample so that all the chloride ions present will react.Ag+ + Cl- AgCl(s) (Ksp = 1.70 × 10−10)Excess WhiteExcess of Ag+ is back titrated with SCN-.
In the reaction MgCI2 plus 2KOH Mg(OH)2 plus 2KCI if 3 moles MgCI2 are added to 4 moles KOH what determines how much Mg(OH)2 is made?
The potassium hydroxide is what we call the limiting reactant. 4 moles of potassium hydroxide react with 2 moles of magnesium chloride. The third mole of magnesium chloride is in excess and has no effect.
How many moles of KBr will be produced from 7 moles of BaBr2?
None, unless there is metallic potassium in the reaction mixture. Assuming excess potassium metal is present then 14 moles of KBr can be produced. 7BaBr2 + excess potassium -----> 14KBr + 7 Ba
In the reaction of silver nitrate with sodium chloride how many grams of silver chloride will be produced from 100 g of silver nitrate when it is mixed with an excess of sodium chloride?
58.9g

What happens when chloride is taken in excess?
vomitting
Why excess barium chloride is added to the filtrate in the preparation of a dry sample of barium sulphate?
Barium chloride in excess is added to be sure that the reaction is complete.
Add an excess of potassium iodide to copper sulphate solution how much is excess?

Excess potassium ion is eliminated from the body by?
Kidney
What happens when excess chloride is consumed?
weakness and vomitting
In the reaction MgCI2 plus 2KOH Mg(OH)2 plus 2KCI if 3 moles MgCI2 are added to 4 moles KOH what determines how much Mg(OH)2 is made?
The potassium hydroxide is what we call the limiting reactant. 4 moles of potassium hydroxide react with 2 moles of magnesium chloride. The third mole of magnesium chloride is in excess and has no effect.
What is the concentration of chloride ion in 229 mL solution if the addition of excess silver nitrate precipitates 8.07 g silver chloride?
If the addition of excess silver nitrate precipitates 8.07 g silver chloride, the concentration of chloride ion in 229 mL solution is .25.
What is the colour given by excess lithium in lithium chloride?
yellow
How many moles of KBr will be produced from 7 moles of BaBr2?
None, unless there is metallic potassium in the reaction mixture. Assuming excess potassium metal is present then 14 moles of KBr can be produced. 7BaBr2 + excess potassium -----> 14KBr + 7 Ba
Why excess concentration of potassium cause increases heart to become dilated and flaccid and decrease heart rate?
because if potassium is
