Hint for post-lab question #2: Since the concentrations of the weak acids and the salts (the conjugate bases of
the weak acids) added are the same, the concentration ratio of the conjugate base
over its acid ([A-]/[HA]) equals the ratio of the volumes of the two added.
For example, in
in the case of buffer a,
= the volume of sodium acetate added/the volume of acetic acid
[A-]/[HA]
added
= 5 mL/5 mL =1

What are the options? i can you if you give them.

So3 that’s what i think

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f.
