Acid go b
The lower the pH level the more acidic it is. The higher the more basic it is. The answer is an acid
an acid has PH scale of 0 to 6
Answer : The correct option is, will decrease and will increase
As we know that the water is made up of the and ions. When a substance with a pH 11.4 that means the solution is basic in nature is added to water, the concentration of ions increase and the concentration of ions decreases.
In the basic solution, the concentration of ions are more than the concentration of ions. So, when a base is added to the water the more ions dissociates in the water as compared to the ions.
Hence, the correct option is, will decrease and will increase
Answer is: H+ will increase and OH− will decrease.
pH = 11.4.
pH = -log[H+].
[H+] = 10∧(-pH).
[H+] = 10∧(-11.4).
[H+] = 4·10⁻¹² mol/L.
[H+] · [OH-] = 1·10⁻¹⁴ mol²/dm⁶.
[OH-] = 0.0025 mol/L.
pH value (potential of hydrogen - [H+]) is a logarithmic scale that specify the acidity or basicity of an aqueous solution.
When pH is greater than seven, aqueous solution is basic, below seven is acidic and when pH is equal seven, solution is neutral.
anything that turns red litmus paper to blue it is an acid and vice versa is true
D . A substance with a pH of 8
pH stands for "Potential for Hydrogen." This is an indicator of a solution's acidity or alkalinity. It is also used to tell which chemicals are great for cleaning.
pH 7 and pH 8 are both considered "neutral pH," thus, solutions with these pH are often used as dishwashing detergents because they do not destroy the surfaces of objects. However, pH 8 is said to be more alkaline in nature. This allows it to destroy the residues, such as fats and oils, in pots and pans. It is the pH of baking soda.
option d is the answer
hope it helps
Firstly, we define pH as the negative logarithm to base 10 of the concentration of hydrogen ions.
Mathematically, we express this as:
pH = -log[H+]
Now let’s us calculate the concentration of hydrogen in each of the pH
For pH 4, we have:
4 = -log[H+]
[H+] = -Antilog(4)
[H+] = 0.0001M
For pH 5,
[H+] = -Antilog(5)
[H+] = 0.00001M
We can see that 0.0001 is greater than 0.00001 and thus it has a greater concentration of hydrogen ions
The answer would be D.
"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence, the electronegativity (or the ability to attract electrons) is lessened."
let the different atoms be x and y. each with four protons and same mass will be represented as follows.
mass number is number of protons + number of neutrons.
since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.
according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .
the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
