What is the pH of an acidic solution?

Chemistry
1 answer:
tiny-mole [99]3 years ago
6 0
The answer is A, between 0 and 7.

In a pH scale from 0 to 14, we can groups these numbers into acidic, neutral, and alkaline. 7 is the neutral pH value, therefore, 0-7 is always acidic, and 7-14 is alkaline.
The smaller the number is, the more acidic the solution will be. This applies same in alkalis, the larger the pH value is, the more alkaline the solution is.

We can measure the pH of solution with many methods, the easiest way include using a pH paper, more advanced and accurate methods includes using a pH meter.

nikklg [1K]
<h3>Answer:</h3>

                      Acids hydrolyze or dissolve in solutions to form <u>Protons</u>.

<h3>Explanation:</h3>

                      Acid are defined according to three different theories and concepts.

                       i)  Arrhenius Concept

                       ii) Lowry Bronsted Theory

                      iii) Lewis Theory

According to Arrhenius Concept of Acid and Base, "Acid is any specie which when dissolved in water ionizes to produce H⁺ ions".

Example:

                                  HCl    →    H⁺₍aq₎  +  Cl⁻₍aq₎

                                  H₂SO₄    →    2 H⁺₍aq₎  +  SO₄²⁻₍aq₎

Proton (H⁺):

                   Hydrogen atom with atomic mass of 1 amu contains one proton and one electron in its first shell. When this single electron is removed from hydrogen atom it is left with only one proton hence, H⁺ is called proton.

Hydrolysis:  

                 In simple, hydrolysis is that reaction in which water molecules are utilized to breakdown a chemical compound.

<h3>Conclusion:</h3>

                     Hence, we can conclude that Arrhenius Acids when added to water are being hydrolyzed by water molecule and yield H⁺ (proton) along with corresponding negative specie.

Liquid octane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . Suppose 97. g of octane is mi
zhannawk [14.2K]

Answer: 61 grams

Explanation:

To calculate the number of moles, we use the equation:

\text{Number of moles of octane}=\frac{\text{Given mass}}{\text{Molar mass}}=\frac{97g}{114g/mol}=0.85moles

\text{Number of moles of oxygen}=\frac{\text{Given mass}}{\text{Molar mass}}=\frac{150g}{32g/mol}=4.69moles

The chemical equation for the combustion of octane in oxygen follows the equation:

2C_8H_{18}+25O_2\rightarrow 16CO_2+18H_2O

By stoichiometry of the reaction;

25 moles of oxygen react with 2 moles of octane

4.69 moles of oxygen react with=\frac{2}{25}\times 4.69=0.37  moles of octane

Thus, oxygen is the limiting reagent as it limits the formation of product and octane is the excess reagent.

25 moles of oxygen produce 18 moles of water

4.69 moles of oxygen produce=\frac{18}{25}\times 4.69=3.38  moles of water.

Mass of water produced=moles\times {\text{Molar mass}}=3.38\times 18g/mol=61g

The maximum mass of water that could be produced by the chemical reaction is 61 grams.

pogonyaev
Cobalt-59 and Cobalt-60 differ in that they have different mass number which means they have different number of neutrons. Isotopes are atoms of the same element with similar atomic number but different mass number. Cobalt-60, has a number of uses, which includes, being used to irradiate food sources as a method of preserving food, used in industrial radiography to detect structural flaws in metal parts among other uses.
