Question

determine the molarity of the given HCl solution by titrating against M/20 NaOH​

Answer 1

Answer:

Explanation:

Determining the molarity of the given HCl solution -

Take known volume of HCl solution and titrate it against NaOH solution of known concentration.

Reaction for this titration is -

HCl + NaOH --> NaCl + H2O

Molarity of HCl solution is determined by formula -

M(HCl)×V(HCl) / M(NaOH)×V(NaOH) = 1/1

M(HCl) = M(NaOH)×V(NaOH) / V(HCl)

M(HCl) = V(NaOH) / 20V(HCl)

Answer 2

The Hydrochloric corrosive arrangement might be titrated against sodium carbonate arrangement utilizing methyl orange marker.

Explanation:

The Hydrochloric corrosive arrangement might be titrated against sodium carbonate arrangement utilizing methyl orange marker. The points when the feeble base is titrated with a solid corrosive arrangement are marginally acidic at the endpoint. Assuming a frail corrosive is titrated with a solid base the arrangement is somewhat essential in light of the fact that the salt shape will be hydrolyzed partially.

The substance responses associated with this titration are given below.

Na2CO3(aq) + 2HCl(aq) → 2NaCl(aq) + CO2(g) + H2O(l)

CO32-(aq) + 2H+(aq) → CO2(g) + H2O(l)

In corrosive base titrations toward the endpoint how much the corrosive turns out to be synthetically identical to how much base is present. In the event of a solid corrosive and a solid base titration toward the endpoint of arrangement, the arrangement becomes nonpartisan.
