HCl solution is always a strong acid solution , so this is also a strong acid solution.
As concentration of solution is quite low , so we can call it weakly acidic (due to low concentration) , but solution is strong acid solution.
HCl is strong acid solution because it completely dissociates in H^+ and Cl^- ions always even if present in low concentration.
You have a 0.001 M HCl aqueous solution. Would you describe this as a strong acid...
QUESTION 2 The strong acid, HCl, is titrated with a strong base, NaOH, in aqueous solution. What is the pH of the titration solution after the addition of 17.94 mL of 0.100 M NaOH to a 50.00 mL of 0.100 M HCI? Write your answer using 3 significant figures,
Predicting pH Imagine you have a 0.125 M aqueous solution of aspirin, an acid drug with pKa = 3.5, in equilibrium. a) Estimate the pH of the solution Hint: Determine if it is an acid or base solution, weak or strong If weak acid/base, first try (H+) = /K,C, or [OH-] = K,C, b) Predict what would happen to the pH when you add more H2 Hint: First figure out what happens to the concentrations HA(aq) + H2O(0) A (aq)...
If you mix 100.0 mL of 0.125 M HCl (strong acid) with 50.0 mL of 0.175 M NaOH (strong base) what will be the pH of the resulting solution? Have you reached the endpoint of the reaction (circle your answer)? YES NO Explain your answer:

What is the pH of a solution that is 0.060 M in potassium propionate (CH3CH2COOK) and 0.085M in propionic acid (CH3CH2COOH)? The Ka for propionic acid is 1.3x10-5.5 3. Suppose you need to prepare a buffer for a pH of 10.6. An acid-base pair (HA/A') to use has...
What results would you expect when a strong acid (HCl) and a weak base (NH4OH) are mixed? Explain.
The addition of a strong acid like HCl to an aqueous solution would result in an increase in pH. both the release of H+ and an increase in pH. both the release of H+ and a decrease in pH. the release of H+ into the solution a decrease in pH. Question 3 1 pts Cohesive forces in liquid water occur when the H atoms on molecules of H2O hydrogen bond to other Hatoms on adjacent molecules of H20. the H...
A solution contains 1M weak acid (AH), 100mM salt ANa (strong electrolyte), and 1mM HCl(strong acid). The pH of the solution is 2. Determine the pKa of the weak acid AH. The dissociation processes are as follows: AH<-> A- + H+, ANa-> A- + Na+, HCl-> H+ + Cl-
