Nitric acid is a strong acid meaning it completely dissociates in water. Therefore, you can say that the concentration of H+ ions in solution is the same as the concentration of the acid (molar concentration). So once you have that, you can use the pH formula to find the pH of the acid.
A patient is suspected of having low stomach acid, a condition known as hypochloridia. To determine whether the patient has this condition, her doctors take a 17.00 mL sample of her gastric juices and titrate the sample with 0.000150 M KOH.

The amount of acid a food creates in your body after you consume it is based on the potential renal acid load of the food — not the pH of the food before you consume it.
We are surrounded by dilute solutions of acids and bases, inside and out. The orange juice and coffee that help us start our day are acidic, and the gastric juices they mix with in our stomach.
Calculate the pH of stomach acid in which [HCl] = 0.148. Expert Answer. 100 %(5 ratings) This problem has been solved! See the answer. Previous question Next question.
In the stomach, however, the solution becomes diluted to a pH between 1 and 2, which corresponds to a hydrochloric acid concentration between 0.1 and 0.01 moles per liter. Secretion Process In the parietal cells, transporter proteins ferry chloride and potassium ions outward across the membrane.
Calculating pH of a Strong Acid – Chemistry. – This makes calculating the hydrogen ion concentration, which is the basis of pH, easier than for weak acids. Here’s an example of how to determine pH of a strong acid. Here’s an example of how to determine pH of a strong acid.
Acids are solutions with a pH value less than 7 whereas bases are solutions with a pH value greater than 7. Pure water is neutral at 25 °C and has the standard neutral pH value of 7. The pH value of a solution can go lower than 0 and greater than 14 in the case of really strong acids and bases.
What Is the Molarity of Stomach Acid? |. – In the stomach, however, the solution becomes diluted to a pH between 1 and 2, which corresponds to a hydrochloric acid concentration between 0.1 and 0.01 moles per liter. Secretion Process In the parietal cells, transporter proteins ferry chloride and potassium ions outward across the membrane.
A 2 on the pH scale (like stomach acid) indicates that the substance is a very strong acid. Strong acids can break things down. So, i Strong acids can break things down.
Now, you were probably given the Ka of the acid, telling you that it is a WEAK acid. That means that it does NOT dissociate (dissolve) completely in water. The Ka at this point is just a number to plug into your equation. To find the concentration of H_3O^+ from the Ka and your equation, simply plug the numbers that you have into this: You can do the exact same thing if its a BASIC solution.
b) Stomach acid has a pH that ranges from 1 to. – b) Stomach acid has a pH that ranges from 1 to 3. What is the hydrogen ion concentration of the most acidic stomach?
pH-dependent plant pigments that can be used as pH indicators occur in many plants, including hibiscus, red cabbage (anthocyanin) and red wine. The juice of citrus fruits is acidic mainly because it contains citric acid.
I would measure the pH of the stomach acid. And as I know that pH is defined by the formula: pH = -log [H+] And I know that stomach acid is HCl and a strong acid.
As with any buffer system, the pH is balanced by the presence of both a weak acid (for example, H 2 CO 3) and its conjugate base (for example, HCO − 3) so that any excess acid or base introduced to the system is neutralized.

The most common method is a pH meter, which involves a pH-sensitive electrode (usually made of glass) and a reference electrode. Acid-base indicators change color in response to different pH values.
