Water acts as solvent and it has no effect on the amount of the acid or the titrating agent.
<span>Also, the concentration of the titrating agent must be known exactly, the amount of solvent is less important (the more diluted it is, the more accurate is the titration).</span>
Answer:
HCl, also known as hydrochloric acid, has a covalent bond. The hydrogen (H) atom shares an electron with the chlorine (Cl) to form the bond.
Explanation:
Consequently, the bonding electrons in hydrogen chloride are shared unequally in a polar covalent bond. The molecule is represented by the conventional Lewis structure, even though the shared electron pair is associated to a larger extent with chlorine than with hydrogen.

Answer:
Atomic number is 8 and mass number is 17.
Explanation:
From the figure,
The number of protons= 8
The number of neutrons = 9
Any atom contains equal number of protons and electrons.Hence, the atomic number of element is 8.
The atomic number eight element in the periodic table is "Oxygen.
And mass number is 17.
Reason is if a cord is cover with rubber and high currents and voltage can cause heat within which can be very harm since it can also handle and melt to a certain degree.
