Answer:
None
Step-by-step explanation:
A high pH is caused by an excess of hydrogen ions over hydroxide ions.
Hydrogen ions are so small that they pass through the pores of an ordinary filter.
Thus, ordinary filtration has no effect on the pH of water.
POH=14-pH
pH=-lg[H⁺]
pOH = 14 + lg0.025 = 12.4
Answer:
Theoretical yield of HI is 512 g.
The percent yield for this reaction is 25%.
Explanation:

Moles of hydrogen gas = 3.0 moles
Moles of iodine gas = 2.0 moles
According to reaction 1 mol of hydrogen gas reacts with 1 mol of iodine gas.
Then 3.0 moles of hydrogen gas reacts with 3.0 mol of iodine gas. But there are 2.0 moles of iodine gas. Hence,Iodine is a limiting reagent. The production of HI will depend upon iodine gas moles.
According to reaction , 1 mol of iodine gas gives 2 moles of HI.
Then 2 moles of iodine gas will give:
of HI
Theoretically we will get 4 moles of HI.
Theoretical yield of HI = 4 mol × 128 g/mol= 512 g
Experimental yield of HI = 1.0 mol
= 1 mol × 128 g/mol= 128 g


The percent yield for this reaction is 25%.
