a.
Interpretation:Whether the given acid base pair HI,I- is a conjugate acid-base pair is to be found out.Corrections are to be made if they are not a conjugate acid base pair.
Concept Introduction:An acid and base pair with the gap of one proton(presence or absence) is called a conjugate acid-base pair.
a.
Answer to Problem 7A
HI and I- are a conjugate acid base pair.
Explanation of Solution
HI is an acid. On removal of a proton it becomes I- which is a Lewis base. There is a difference of a single proton between the two of them so they are a conjugate acid base pair.
b.
Interpretation:Whether the given acid base pair H3PO4,PO43- is a conjugate acid-base pair is to be found out.Corrections are to be made if they are not a conjugate acid base pair.
Concept Introduction:An acid and base pair with the gap of one proton(presence or absence) is called a conjugate acid-base pair.
b.
Answer to Problem 7A
H3PO4,PO43- is not a conjugate acid base pair. The correct conjugate acid base pair is H3PO4,H2PO4-
Explanation of Solution
H3PO4,PO43- have a proton difference of 3 so they are not a conjugate acid base pair. H3PO4,H2PO4- have a proton difference of 1 so it will be the correct conjugate acid base pair for this case.
c.
Interpretation:Whether the given acid base pair HClO,HClO2 is a conjugate acid-base pair is to be found out.Corrections are to be made if they are not a conjugate acid base pair.
Concept Introduction:An acid and base pair with the gap of one proton(presence or absence) is called a conjugate acid-base pair.
c.
Answer to Problem 7A
HClO,HClO2is not a conjugate acid base pair. The correct conjugate acid base pair is HClO, ClO- and HClO2,ClO2-
Explanation of Solution
HClO and HClO2are both separate acids and cannot be conjugate acid base pair for each other. They will form two separate conjugate acid base pairs which will have proton difference of 1 namely HClO, ClO- and HClO2,ClO2-
d.
Interpretation:Whether the given acid base pair H2CO3,CO32- is a conjugate acid-base pair is to be found out.Corrections are to be made if they are not a conjugate acid base pair.
Concept Introduction:An acid and base pair with the gap of one proton(presence or absence) is called a conjugate acid-base pair.
d.
Answer to Problem 7A
H2CO3,CO32- is not a conjugate acid base pair. The correct conjugate acid base pair is H2CO3,HCO3-
Explanation of Solution
H2CO3,CO32- have a proton difference of 2 so they are not a conjugate acid base pair. H2CO3,HCO3- have a proton difference of 1 so it will be the correct conjugate acid base pair for this case.

- Please correct answer and don't use hand ratingarrow_forwardDon't used hand raitingarrow_forwardReagan is doing an atomic absorption experiment that requires a set of zinc standards in the 0.4- 1.6 ppm range. A 1000 ppm Zn solution was prepared by dissolving the necessary amount of solid Zn(NO3)2 in water. The standards can be prepared by diluting the 1000 ppm Zn solution. Table 1 shows one possible set of serial dilutions (stepwise dilution of a solution) that Reagan could perform to make the necessary standards. Solution A was prepared by diluting 5.00 ml of the 1000 ppm Zn standard to 50.00 ml. Solutions C-E are called "calibration standards" because they will be used to calibrate the atomic absorption spectrometer.
