WebUnder ordinary circumstances, our bodies lose about 2.5 liters of water a day through urination, and evaporation from our skin and through respiration. To counter this, we consume about 2.5 liters of water a day in the form of food and drink, thereby maintaining a balance of body fluid level. WebAs shown in the equation, dissociation makes equal numbers of hydrogen (H + ^+ + start superscript, plus, end superscript) ions and hydroxide (OH − ^-− start superscript, minus, end superscript) ions.While the hydroxide …
