In an oxidation-reduction reaction, the oxidized reagent <u>gains electrons</u>, and the reduced reagent<u> looses electrons.</u>

<u></u>

<h3>Oxidizing and reducing reagent:</h3>

In a chemical process, an oxidizing agent, also known as an oxidant, obtains electrons and becomes reduced. The oxidizing agent often referred to as the electron acceptor, is typically in one of its higher oxidation states since it will receive electrons and be reduced. Halogens (such as chlorine and fluorine), oxygen, and hydrogen peroxide are typical examples of oxidizing agents (H₂O₂).

A reducing agent is a material that, in a redox process, loses electrons to other substances and undergoes oxidation to a higher valency state. Because it provides its electrons to fluorine, hydrogen functions as a reducing agent, decreasing fluorine. The metals found in the earth, formic acid, and sulfite compounds are a few examples of reducing agents.

A cleaning product company is having trouble with the phi control of one of their products. The prod basic but the pH is too hig

Mrac [35]

Answer:

Option B.

Explanation:

Obviously, a cleaning agent companies is going to be a producer of cleaning agents which are chemical substance which are used for the main purpose of removing unwanted particles (dirt).

For this particular Question, option ''B'' is correct because upon the addition of H2O, there will surely be changes in the numbers of ions in the cleaning agents.

From the Question above, we have that the cleaning agents has pH which is too high, therefore in order to reduce the pH of the cleaning agents, water will be used to mix the product or cleaning agents. Upon the addition of water there will be decrease in OH^-.

Sholpan [36]

Answer:

Strait.

Explanation:

After a fast online search, I've found that the list of words are:

Athens

Age of Pericles

satraps

tyrant

Cyrus the Great

hoplites

Parthenon

peninsula

upper-class Athenian women

strait

Well, the definition is:

"A narrow body of water with land on both sides"

This is something like a river, so we need to find which one of these words means something like river.

To do it, let's look at short definitions of each word:

Athens: This is the capital city of Grece. (Isn't the correct option)

Age of Pericles: This refers to a historical period (isn't the correct option)

Satraps: Were governors in the Persian empire (Isn't the correct option)

Tyrant: Refers to a cruel leader (Isn't the correct option)

Cyrus the Great: Was the founder of the Achaemenid Empire (isn't the correct option)

Hoplites: A citizen-soldier (isn't the correct option)

Parthenon: A construction in Grece (isn't the correct option)

Peninsula: A small body of land surrounded mostly by water, but connected to land (isn't the correct option)

upper-class Athenian women: It is self-explained, this isn't the correct option.

Strait: This refers to a narrow passage of water that connects two larger areas of water (like two seas, for example)

Then this one is the correct option.

By titration, it is found that 47.5 mL of 0.146 M NaOH(aq) is needed to neutralize 25.0 mL of HCl(aq). Calculate the concentrati

OleMash [197]

Answer:

The correct answer is 0.277 M HCl

Explanation:

NaOH is a strong base and HCl is a strong acid. NaOH reacts with HCl to form a salt (NaCl) and water via a neutralization reaction, as follows:

NaOH + HCl → NaCl + H₂O

At the equivalence point, the moles of NaOH added is equal to the moles of HCl present in the solution to be titrated. Moreover, the moles can be calculated as the product of the concentration of base or acid (Cb or Ca) and the volume (Vb and Va), as follows:

moles NaOH = moles HCl

Cb x Vb = Ca x Va

Thus, we calculate the concentration of HCl (Ca), as follows:

Ca = (Cb x Vb)/Va = (0.146 M x 47.5 mL)/(25.0 mL)= 0.277 M
