86.66 % by weight of ascorbic acid in the tablet, when 0. 1220 g vitamin c tablet was dissolved in acid. This required 11. 50 ml of 0. 01740 m to reach the endpoint.
A balanced chemical reaction is an equation that has equal numbers of each type of atom on both sides of the arrow.
→
So, the balanced chemical equation for the reaction will be:
→
That means, 3 mol of of ascorbic acid reacts with 1 mol of
Moles of available is 0.0174 X 0.0115 =0.0002001 mol
Moles of ascorbic acid to be yielded should be 3 X 0.0002001 =0.0006003
So, percent mass of ascorbic acid in the tablet will be:
(0.1057 / 0.1220) X 100 %
=86.66 %
Hence, the third option is the correct answer.

<u>Answer:</u> The weak bond having slightly positive region and a slightly negative region is polar covalent bond.
<u>Explanation:</u>
Covalent bond is defined as the bond which is formed by the sharing of electrons between the atoms. <u>For Example:</u> HCl, etc..
They are of two types:
- <u>Polar covalent bond:</u> This bond is formed when difference in electronegativity between the atoms is present. When atoms of different elements combine, it results in the formation of polar covalent bond.
In this bond, a dipole is created. More electropnegative atom will have a slight negative charge and less electronegative atom will have a slight positive charge. For Example: etc..
- <u>Non-polar covalent bond:</u> This bond is formed when there is no difference in electronegativity between the atoms. When atoms of the same element combine, it results in the formation of non-polar covalent bond. For Example:
etc..
Hence, the weak bond having slightly positive region and a slightly negative region is polar covalent bond.
