<u>Answer:</u> The pH of the resulting solution will be 3.60
<u>Explanation:</u>
Molarity is calculated by using the equation:
......(1)
We are given:
Molarity of formic acid = 0.100 M
Molarity of potassium formate = 0.100 M
Volume of solution = 420 mL = 0.420 L (Conversion factor: 1 L = 1000 mL)
Putting values in equation 1, we get:
Molarity of KOH = 1.00 M
Volume of solution = 7 mL = 0.007 L
Putting values in equation 1, we get:
The chemical equation for the reaction of formic acid and KOH follows:
I: 0.042 0.007 0.042
C: -0.007 -0.007 +0.007
E: 0.035 - 0.049
Volume of solution = [420 + 7] = 427 mL = 0.427 L
To calculate the pH of the acidic buffer, the equation for Henderson-Hasselbalch is used:
.......(2)
Given values:
Putting values in equation 2, we get:
Hence, the pH of the resulting solution will be 3.60
2. 15.65 grams of KCl is formed if 25.0 g of Potassium Chlorate, KClO3, decompose.
3. 2.17 moles of H2 gas produced when 100.0 grams of Na is added to the reaction.
4. 7.5 moles of Hydrogen, H2, are needed to react with 2.5 moles of Nitrogen, N2.
Explanation:
2. The balanced equation for the chemical reaction is:
2KClO3 ⇒ 2KCl + 3O2
Data given:
mass of KClO3 = 25 grams, atomic mass of KClO3 = 122.55 grams/mole
KCl produced =? atomic mass of KCl = 74.55
number of moles =
=
number of moles = 0.20 moles of KCO3
2 moles of KClO3 decomposes to give 2KCl
0.21 moles of KClO3 decomposes to give x moles of KCl
=
x = 0.21 moles of KCl
mass of KCl = 0.21 x 74.55
= 15.65 grams of KCl is formed.
3. data given:
2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g)
mass of Na added = 100 grams, atomic mass of Na = 22.98 grams/mole
moles of H2 =?
Number of moles of Na =
=
number of moles of Na = 4.35 moles
2 moles of Na gives 1 mole of H2
4.35 moles of Na will give x moles
=
2x = 4.35
x = 2.17 moles of hydroden gas is produced.
4. Data given:
the balanced chemical equation:
N2 + 3H2 → 2NH3
Number of moles of N2 2.5
from the reaction
1 mole of N2 reacts with 3 moles of H2
The molar ratio of the reactant is 1:3
so, =
x = 7.5 moles of H2 will react with 2.5 moles of N2.
