Answer:
It is an example of Arrhenius acid-base reaction.
Explanation:
- In this reaction, water acts as an Arrhenius base because it consumes a proton from sulfuric acid.
- In this reaction, sulfuric acid acts as an Arrhenius acid because it donates a proton to water.
- Lone pair on oxygen atom in water is used to bind the proton obtained from sulfuric acid.
- Proton attached to -OH group in sulfuric acid is being donated because it is loosely bounded to oxygen atom due to high polarity of O-H bond.
- Reaction:
![H_{2}O+H_{2}SO_{4}\rightarrow H_{3}O^{+}+HSO_{4}^{-}](https://tex.z-dn.net/?f=H_%7B2%7DO%2BH_%7B2%7DSO_%7B4%7D%5Crightarrow%20H_%7B3%7DO%5E%7B%2B%7D%2BHSO_%7B4%7D%5E%7B-%7D)
- Mechanism has been shown below.
The volume of oxygen produced can be measured using the gas syringe method. The gas collects in the syringe, pushing out against the plunger. The volume of gas that has been produced can be read from the markings on the syringe.
Explanation:
It is given that volume of
is 300 mL and molarity is 0.200 M.
Volume of NaCl is 200 mL and molarity is 0.050 M.
The chemical reaction will be as follows.
![PbCl_{2}(s) \rightleftharpoons Pb^{2+}(aq) + 2Cl^{-}(aq)](https://tex.z-dn.net/?f=PbCl_%7B2%7D%28s%29%20%5Crightleftharpoons%20Pb%5E%7B2%2B%7D%28aq%29%20%2B%202Cl%5E%7B-%7D%28aq%29)
for
is given as
.
As, molarity is number of moles present in liter of solution.
Hence, moles of
(aq) will be calculated as follows.
moles of
(aq) = ![0.300 L \times 0.200 M](https://tex.z-dn.net/?f=0.300%20L%20%5Ctimes%200.200%20M)
= 0.06 mol
= ![\frac{0.06 mol}{0.5 L}](https://tex.z-dn.net/?f=%5Cfrac%7B0.06%20mol%7D%7B0.5%20L%7D)
= 0.120 M
Mole of
=
= 0.010 M
Now, Q =
= ![0.120 \times (0.010)^{2}](https://tex.z-dn.net/?f=0.120%20%5Ctimes%20%280.010%29%5E%7B2%7D)
=
As, Q <
hence, there will be no formation of
precipitate.
