Answer:
0.02685 M is the molarity of the barium hydroxide solution.
Explanation:
To calculate the concentration of acid, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is
mm.
We are given:
Putting values in above equation, we get:
0.02685 M is the molarity of the barium hydroxide solution.
Answer: Option (d) is the correct answer.
Explanation:
According to Bronsted-Lowry an acid is defined as the specie which is able to donate hydrogen ions when dissolved in water.
For example,
On the other hand, bases are the species which are able to donate hydroxide ions when dissolved in water.
For example,
Thus, we can conclude that a definition of an acid is that it donates H ions when dissolved in water.
Answer:
The balanced half reaction in an acidic medium is :
Explanation:
While balancing the half-reaction in an acidic medium, we will first balance oxygen atoms by adding water:
1) Adding 1 water molecule on product side to balance oxygen atoms.
Now balance hydrogen atom by adding .
2) Adding 2 hydrogen ions on reactant side to balance hydrogen atoms.
Now balance the charge adding electrons on the side where positive charge is mor.
3) Adding 1 electrons on reactant side to balance charge of the overall reaction:
The balanced half reaction in an acidic medium is :
