Answer : The resulting solution will have a pH of 7.
Explanation:
Whenever acid and base reacts with each other to form water molecule is called Neutralization reaction. This water molecules is formed from the hydronium ion () from acid and hydroxide ion(
) from base.
When the equal volumes of acid and base of equal strength are combined, the resulting pH of the solution becomes 7.
The pH 7 value means that the solution is neutral.
Answer:
The options e and d are correct.
Explanation:
Mass of NiO = 7.5 g
Moles of NiO =
Moles of sulfuric acid = n
Volume of sulfuric acid ,V= 50 mL = 0.050 L
Molarity of sulfuric acid ,M = 6 mol/L
According to reaction, 1 mole of NiO reacts with 1 mole of sulfuric acid.
Then 0.10 moles of NiO reacts with :
of sulfuric acid.
As we can see that sulfuric acid is in excess amount, so the amount of the product will depend upon amount of NiO.
According to reaction, 1 mole of NiO gives with 1 mole of .
Then 0.10 moles of NiO wil give :
of
.
Molar mass of = 154.75 g/mol
Mass of 0.10 moles of :
= 154.75 g/mol × 0.10 mol = 15.475 g
Theoretical mass of = 15.475 g
Experimental yield of = 17.4 g
Percentage yield :
Percentage yield of :
Moles of = 262.85 g/mol × 0.10 mol = 26.285 g
Experimental yield of = 17.4 g
Percentage yield of :
