What is [Al(H2 O)5(OH)2+] in a 0.15-M solution of Al(NO3)3 that contains enough of the strong acid HNO3 to bring [H3O+] to 0.10 M? What is the (OH^-) of a 0.00756 M HNO_3 solution? What are the tw...
What is the [H3O+] of a buffer that consists of 0.35 M CH3CH2COONa and 0.15 M CH3CH2COOH? (Ka=1.3×10−5) Buffer Solution: A weak Bronsted-Lowry acid will reversibly transfer hydrogen ions (protons) to water molecules in an aqueous solution, resul...
SAS IT Resource Management is the new name for IT Service Vision. You may see references in our older documentation to its former name. The hotfixes issued during the 2.7 release cycle are cumulative. That is, hotfix 27IS08 contains all the changes that were contained within hotfix 27IS07....
For those of you who watched the DNC production, it will be easy to understand why there are so many long-standing Democrats who are now finding themselves outside the fray of the new Democratic Party. These are the voters who will make a difference in the upcoming national election…These...
The value of {eq}K_a {/eq} for hypochlorous acid is {eq}3.50 \times 10^{-8} {/eq}. What is the value of {eq}K_b {/eq} for its conjugate base, {eq}ClO^- {/eq}? Weak Acid-Base Conjugate Pair: The partial dissociation of a we...
c. HClO2 d. HClO3 e. none of the above Basic Organic Chemistry and its Compounds A weak base does not completely dissociate or they partially dissociate into water. Hypochlorous acid is a weak base which dissociate into ClO−. They are formed when c...
How can you estimate the pH range of an indicator's color change? A certain indicator, HA, has a Ka value of 0.000025. The protonated form of the indicator is red and the ionized form is yellow. a. What is the pKa of the indicator? b....
