Based on the pH of your drug, if your drug was in a high concentration in the blood,how would it affect the pH of your blood. Would it cause acidosis or alkalosis, and how would you treat this? drug Lipitor ph is 7 it's acidosis?
A buffer donates OH- ions when conditions become too basic and accepts OH- ions when conditions become too acidic. is an acid that is used to offset overly basic conditions in the body. donates H+ ions when conditions become too basic and accepts H+ ions when conditions become too acidic. is a base that is used to offset overly acidic conditions in the body.
Define pH scale, acid, base, and buffer. How do buffers reduce changes in pH when hydrogen ions or hydroxide ions are added to a solution? Why is this phenomenon important in organisms?

In the course of a hypothetical meal, the stomach expands from 0.25 liters to 1.25 liters. If we assume that no buffering occurs and no acid is produced from the stomach contents, how much acid must be secreted to maintain pH = 1.0? How many grams of ATP would be consumed in the production of that acid?
In a 0.1000 M acetic acid solution at 25 degrees celsius , the acid ionizes to the extent of about 1.34 %. Since each molecule of acetic acid which ionizes produces 1 H+ ion and 1 C2H3O2- ion, the concentration in the solution are: HC2H3O2 < -----------> H+ + C2H3O2-

Three proteins with an overall charges of 0, -5, and -8 are passed through an anion exchange column equilibrated in a buffer with low ionic strength and eluted with an increasing gradient of salt in a buffer. Which protein will elute last from the column? 1. Protein with no charge. 2. Protein with eight negative charges. 3. Protein with five negative charges. 4. Both charged proteins will elute at the same time.
In a hospital laboratory, a 10.0 mL sample of gastric juice, obtained several hours after a meal, was titrated with 0.01 M NaOH to neutral pH of 7.0; 72.0 mL of NaOH was required for this titration. The patient’s stomach contained no ingested food or drink, thus assume that no buffers were present. What was the pH of the 10.0 mL gastric juice sample before titrating with NaOH?
