Answer : The correct option is, The concentration of the acid.
Explanation :
Molarity : Molarity is defined as the moles of solute present in one liter of the solution. Or it is defined as the concentration of solute present in one liter of solution.
The unit of molarity is, (M) i.e, mole/liter. It is also known as molar concentration.
Molarity of 0.01 M means, 0.01 concentration of the acid present in the solution.
Therefore, the 0.01 M refer to the concentration of the acid.
The correct answer among the choices given above is the last option. When an acid reacts with an active metal, hydrogen gas is produced. The hydrogen in acid is displaced by the metal yielding hydrogen gas.
Mg + 2HCl = MgCl2 + H2
Cation means a positively charged ion. Anion is a negative one
Because they follow the octet rule and the outer most electrons, the valence electron shell is full.
