In a titration experiment, 13.0 mL of an aqueous HCl solution was titrated with 0.2 M NaOH solution. The equivalence point in th
1 answer:
Answer:
The molarity of the HCl solution is 0.17M
Explanation:
When a titration occurs between an acid and a base it is called neutralization.
The formula to calculate the concentration of the acid is:
Ca*Va=Cb*Vb
where Ca and Cb are the concentrations of the acid and the base respectively and Va and Vb are the volumes of the acid and the base.
As HCl is an acid, solve the equation for Ca:
Replacing values:
Therefore the molarity of the HCl solution is 0.17M

Answer: When maganese dioxide is added to hydrogen chloride you get water maganese dichloride and chlorine gas then balanced equation is .
Explanation:
The word equation is given as maganese dioxide is added to hydrogen chloride you get water maganese dichloride and chlorine gas.
Now, in terms of chemical formulae this reaction equation will be as follows.
Here, number of atoms on reactant side are as follows.
- Mn = 1
- O = 2
- H = 1
- Cl = 1
Number of atoms on product side are as follows.
- Mn = 1
- O = 1
- H = 2
- Cl = 4
To balance this equation, multiply HCl by 4 on reactant side and multiply by 2 on product side. Therefore, the equation can be rewritten as follows.
Hence, number of atoms on reactant side are as follows.
- Mn = 1
- O = 2
- H = 4
- Cl = 4
Number of atoms on product side are as follows.
- Mn = 1
- O = 2
- H = 4
- Cl = 4
Since, this equation contains same number of atoms on both reactant and product side. Therefore, this equation is now balanced equation.
Thus, we can conclude that when maganese dioxide is added to hydrogen chloride you get water maganese dichloride and chlorine gas then balanced equation is .
