Acid-Base Indicator | Definition, Concept & Examples from Chapter 11 / Lesson 11 70K Learn about acid-base indicators. Understand what acid-base indicators are, how they work to determine if a solution is acidic or basic, and see the examples. Related to...
What is the pH of a buffer solution of 0.125M acetic acid and 0.250M sodium acetate at 25 ^{\circ}C? (The pKa of acetic acid is 4.76) How are Ka and Kb values of an acid and base used to determine the acidic or basic nature of their a...
The intrinsic solubility of delavirdine in water is 0.86 μg/mL and demonstrates a pH-dependent solubility profile (higher solubility at acidic pH 1.2). Different salts of delavirdine viz. tosylate, HCl, HBr, mesylate, etc., were prepared to improve the solubility of a drug. The ...
pH describes how acidic or basic a solution is. Whether an aqueous solution reacts as an acid or a base depends on its hydrogen ion (H+) content. In fact, the term "pH" originates from Latin and is an acronym for "potentia hydrogenii" - the power of hydrogen. ...
Merck silica gel plates (60F-254) using ultraviolet light as visualizing agent and aqueous ammonium cerium nitrate/ammonium molybdate or basic aqueous potassium permanganate as developing agent. E. Merck silica gel (60, particle size 0.040–0.063 mm) was used for flash column chromatography. ...
Aluminium hydroxide is amphoteric, i.e., it has both basic and acidic properties. Closely related are aluminium oxide hydroxide, AlO(OH), and aluminium oxide or alumina (Al2O3), the latter of which is also amphoteric. These compounds together are the major components of the aluminium ore ...
1. Would you expect a solution of iron(III) nitrate to be acidic, basic, or neutral? Why? If the solution is acidic or basic, be sure to fully explain how one of the ions acts as an acid or base. 2. Which of the...
Of equal importance, clinical problems may be caused by the induction of the hepatic enzymes, altering the metabolism of other drugs or compounds. As weak acids, barbiturates tend to ionize in a basic solution, but remain non-ionized in an acid solution. Since only the non-ionized drug can...
Why is groundwater acidic? Why use methyl orange instead of phenolphthalein as a pH indicator? Why is there a need for a very strong base to encourage nucleophilic attack in intramolecular? Explain why pyridine is basic at nitrogen and pyrrole is not, and explain why pyrrole is protonated only...
Is NaOH an acid, base, or salt? Is Nh4Br an acid or a base? Does soda water contain sodium bicarbonate? Is bread soda and bicarbonate of soda the same thing? How much sodium bicarbonate is in baking soda? Are alkaline solutions acidic or basic? How do you remove bicarbonate from water...
