Alkali Metals (Group 1) elements experience an increase in the vigour of their reaction in water as they go down the group (as the atomic number increase). As such the most reactive Alkali Metal would be FRANCIUM, which is at the base of Group One.
Quite frankly, you do not want Francium to react with water- that's a huge explosion on your hand.

<em>Calculate the pH of the following substances formed during a volcanic eruption: </em>
<em>• Acid rain if the [H +] is 1.9 x 10-5 </em>
<em>• Sulfurous acid if [H +] = 0.10 </em>
<em>• Nitric acid if [H +] = 0.11</em>
<em />
<h3>Further explanation </h3>pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.
pH = - log [H⁺]
- pH acid rain
- pH Sulfurous acid
- pH Nitric acid
The empirical formula for the given compound has been . Thus, option C is correct.
The empirical formula has been the whole unit ratio of the elements in the formula unit.
<h3>Computation for the Empirical formula</h3>The given mass of Sulfur has been, 50.05 g
The given mass of oxygen has been 49.95 g.
The moles of elements in the sample has been given by:
- Moles of Sulfur:
The moles of sulfur in the unit has been 1.56 mol.
- Moles of Oxygen:
The moles of oxygen in the unit has been 3.12 mol.
The empirical formula unit has been given as:
Thus, the empirical formula for the given compound has been . Thus, option C is correct.
