1. A
peer-reviewed scientific journal articles.
is usually based on either past experiences or information gained from reading
2.
variables are kept the same to maintain consistent testing conditions across all
experimental samples.
3.
provides a quick, albeit inaccurate, means of obtaining the pH of a solution.
4. Substances whose pH values are above 7.00 are considered
; substances whose pH
values are below 7.00 are considered
5. During a
reaction, molecule B receives an electron(s) from molecule A, leaving
molecule A oxidized.
6. The
reagent is used to detect the presence of complex sugars (ex. starch) in
solutions.
7. Reducing sugars, such as glucose, will always react with Benedict's reagent because these
sugars have a(n)
functional group.
8.
are molecules which donate protons (H+) in solution very easily.

Expert Solution

Step 1

pH is the negative log of H⁺ions concentration. It indicates the acidity of a solution. When the H+ ions concentration is high, then the solution is acidic and pH would be less. If H+ concentration is low then the pH would be high and hence the solution would be basic.

Oxidation is the loss of electrons from the molecules, atom or ion. It increases the oxidation state of molecule. It is called a reducing agent because it reduces the other molecule by donating electrons. On the other hand, the reduction is the gain of electron to the molecule, atom or ion. It decreases the oxidation state of the molecule. It is called oxidizing agent because it receives electrons from the atom making it oxidized.
