Answer:
It is not possible to have 100 percent pure water. Therefore the success rate is not certain
Explanation:
Naturally, pure water does not exist. Water is a universal solvent. As water falls in to the earth as rain, from the atmosphere water picks up particles and minerals. Immediately water hits the ground it reacts with minerals from soil upon which it lands and then it enters into streams and rivers.
Hundred percent pure water is dangerous to life, because it has no minerals which makes it corrosive, if a hundred percent pure water enters the body it will suck off the minerals in the body.
The politician should make a promise of hundred percent pure water to the people in the industrial sector and laboratories because that is where it is useful.
