Answer:
Swimmers health.
Explanation:
The pH is the measure of the concentration of the ions H⁺ (pH = -log[H⁺]), and it determines if the substance is acidic, basic or neutral. If pH = 7, it's neutral, if it's below 7 it's acidic, and if it's above 7, it's basic.
In pool water, chlorine is added to disinfect it, by killing microorganisms. The pH of the water affects the action of the chlorine, and for a better result in disinfection, it must be between 7.0 and 7.6, so the disinfection will happen and the swimmers' health will be protected.
Answer:
A pair of elements will most likely form an ionic bond if one is a metal and one is a nonmetal. These types of ionic compounds are composed of monatomic cations and anions.
The reason why perchloric acid is more acidic that ethane is because the hydrogen in perchloric acid is bonded to oxygen which is more electronegative than carbon.
The acidity of a substance depends largely on the ease with which the X-H bond is broken. If the electron density is tilted towards the atom X, then the X-H bond is weaker and the substance is more acidic.
The polarity of the X-Y bond depends on the electronegativity of X. In the case of perchloric acid and ethane, oxygen is more electronegative than carbon hence the O-H bond in perchloric acid is more easily broken than the C-H bond in ethane.
