Question

For making Ag from AgNO₃, which of the following is used
(a) PH₃
(b) phosphonium iodide
(c) Na₂CO₃
(d) NH₃

Answer 1

NH3 IS CORRECT ANSWER..............

Answer 2

I titrate something with 1 molar AgNO3, adding 50 ml of AgNO3 solution... How would I calculate how many mols of Ag that equate

What I have so far is that 1 M means that there is 0.05 mol of AgNO3 in that 50 ml sample (M = mols/L). So then how many mols of Ag are there in 0.05 mol of AgNO3? Is there just 0.05 mols of Ag in AGNO3 or do I need to somehow take into consideration the proportion of the rest of the elements?

Thank you!!!
