Blood Loss. Blood loss is the most common cause of anemia, especially iron-deficiency anemia. Blood loss can be short term or persist over time. Heavy menstrual periods or bleeding in the digestive or urinary tract can cause blood loss. Surgery, trauma, or cancer also can cause blood loss.
second most common cause of acid-base imbalance. recognized by low blood pH and HCO3- levels. indicated by rising blood pH and HCO3- levels, is much less common than metabolic acidosis. typical causes are vomiting of the acidic contents of the stomach and intake of excess base.
In an acid-base titration, addition of titrant near the equivalence point causes the solution pH to change drastically. This pH change is detectable with indicators that change color as a function of pH. Indicators are weak acids that change color when they gain or lose their acidic proton(s).or titration of a strong acid with a strong base, the equivalence point occurs at a pH of 7. To reach the equivalence point in this example required 0.0350 mL of titrant, or 0.00350 moles of OH-. The titration shows that there were 0.00350 moles of acid in the original solution.
