The information given in the question is not enough to determine the acidity of the solution. This is because, acidity can only be found with the equation: pH = -log [H+].
In order to determine the acidity of the solution, the half titration point value is needed, this will make it possible to determine the value of H30+. If the half point titration value is known, then Ka will be equivalent to pH and the value will be evaluated using the equation: - log (1.6 * 10^-10).
For example, certain medications may influence the results of the test.
Drug test can show the presence of illicit or prescription drugs on hair samples, although the person has not used these drugs.
Some of false positive drug use is because of this medications: antihistamines, decongestants, antibiotics, antidepressants, analgesics and antipsychotics.
Answer:
Ba(NO₃)₂ (aq) + H₂SO₄ (aq) → BaSO₄ (s) + 2HNO₃ (aq)
Explanation:
The equation bellow can be explained by the dissociation of each specie:
Ba(NO₃)₂ (aq) → Ba²⁺ (aq) + 2NO₃⁻ (aq)
H₂SO₄ (aq) → 2H⁺ (aq) + SO₄²⁻ (aq)
The reaction will lead to the formation of solid barium sulfate and nitric acid.
