- Iodine values change during oil hydrogenation. Why these values change during hydrogenation and why would one wish to hydrogenate edible oils?Define the following:- pH- Buffer- pKaA 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 18.00 mL sample of her gastric juices and titrate the sample with 4.85 × 10-4 M KOH. The gastric juice sample required 1.26 mL of the KOH titrant to neutralize it. Calculate the pH of the gastric juice sample. Assume the sample contained no ingested food or drink which might otherwise interfere with the titration. pH = For the patient to be suffering from hypochloridia, the pH of the gastric juices from the stomach must be greater than pH 4. Does the patient have hypochloridia? unable to determine no yes
- Calculate the boiling points of a 8.50 m aqueous solution of fructose. Boiling point constants can be found in the list of constant. Tb= In CelsiusWhy is picric acid used for burns? Explain the principle involvedWhich set of conditions will give the product shown in this reaction? Br KOH, ethanol and heat water/acetone and heat tert-butoxide/tert-butyl alcohol tert-butyl alcohol and heat methoxide/methanol
- If a less concentrated initial solution of socium bicarbonate was used in beaker C, would that solution require more or less bicarbonate to neutralize the acid? Why?Indicate whether a solution will have more OH- or H+if the value of the solution is 10.Define the term buffer. Explain the difference between carbonic acid (H2CO3) and hydrochloric acid (HCl). Can they both be used as buffers? Why or why not.
- Ionic interactions are weaker in water than they are in an anhydrous medium. Describe how water reduces the strength of these interactions.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 18.00 mL sample of her gastric juices and titrate the sample with 3.94 x 10-4 M KOH. The gastric juice sample required 6.60 mL of the KOH titrant to neutralize it. Calculate the pH of the gastric juice sample. Assume the sample contained no ingested food or drink which might otherwise interfere with the titration. pH = Enter numeric value For the patient to be suffering from hypochloridia, the pH of the gastric juices from the stomach must be greater than pH 4. Does the patient have hypochloridia? no O unable to determine O yesWhat is the purpose of: A. The concentrated salt solution? B. adding isopropyl alcohol to the solution?
