Why does the pH change rapidly at the equivalence point of a titration?
The equivalence point represents a region where the amount of acid to base (or base to acid) concentration is equal. Before the equivalence point there is a greater amount of acid (or base, depending on the titration). After the titration there is a greater amount of base (or acid). This reverse in dominance results in a dramatic change in pH.
Why is the amount of guanine always equal to the amount of cytosine?
Amount of guanine is always equal to cytosine
What do electrons have that protons always have in equal magnitude?
Charge
What guantities are always equal to an elements atomic number?
Mass
A conversion factor is a fraction that is always equal to what number?
The answer is "1".
What is the pH at the stoichiometric point of the titration of 25.0 mL of aqueous hypochlorous acid with 0.20 M KOH aq?
The equivalence or stoichiometric point of a titration of a strong acid versus a strong base is always equal to pH 7.
What is the difference between equivalent point and end point in analytical chemistry?
The equivalence point is the point in a titration when the amount of added standard reagent is chemically equal to the amount of analyte. The end point is the point in a titration when a physical change occurring immediate after the equivalence point
Are the values of phi and phi equal?
Yes, two things that are the same are always equal.
How do you divide a circle in equal pieces?
Starting at one point of the circle, draw a straight line through the center of the circle to the other side. This line is called a diameter. It will divide the circle into 2 equal pieces.Now, if you want to divide the circle into any number N of equal pieces, follow these steps in orderdivide the diameter into N equal segments,from one endpoint of the diameter, draw half circles towards every endpoint of the equal segments,flip the circle,from the other endpoint of the diameter, draw again half circles towards every endpoint of the equal segment (but now filling the other side of the circle).The resulting parts of the circle have equal area.
What is the purpose of a titration?
The purpose of a titration is to find the equivalence point (stoichiometric point) of a solution. At the equivalence point, the moles of the titrant and analyte are equal to one another. At the midpoint of the solution, the pKa value is equal to the pH value.
What is formed by two intersecting lines or by two rays with a common endpoint?
vertical opposite equal angles
What is a straight path that extends in one direction and has one endpoint?
This is called a "ray". (It is equal to one half of a line.)
The diagonals of a kite are?
Perpendicular and the one for which each endpoint touches only sides of equal length bisects the other.
What is true when a buffer is formed during a titration?
There are nearly equal amounts of a conjugate acid-base pair.
What two things always form when an acid is neutralized by a base of equal strength?
Water and a salt.
