The concentration of the hydrogen dissociated into the solution gives the pH. When the solution has a pH of 5.6 then, the concentration of H⁺ is 2.51 × 10⁻⁶.
The estimation of the acidic and alkalinity of the solution based on the amount of the dissociated hydrogen or the hydronium ions in the solution gives the pH.
It is measured with the help of the pH scale that indicates the range of the acids and bases along with neutral. The formula of the pH includes the negative logarithm of the hydrogen ion concentration. pH is calculated as,
pH = - log [H⁺]
Given,
pH = 5.6
Substituting values above the concentration are calculated as,
pH = - log [H⁺]
5.6 = -log [H⁺]
[H⁺] = 10⁻⁵°⁶ ≈ 0.0000025
= 2.51 × 10⁻⁶
Therefore, the hydrogen concentration in solution with pH 5.6 is equivalent to 2.51 × 10⁻⁶.

Answer:
Hi there!
The answer to this question is 2.5118X10^-6
Explanation:
The formula to solve this is 10^-pH
When a pure substance undergoes chemical change, the pure substance changes in chemical composition.
Chemical change is any change that involves the formation of new substances or products and it is not easily reversible.
A pure substance is any substance that has a definite chemical composition.
However, when a pure substance undergoes chemical change, the chemical composition of the substance is changed to form new products.

Answer
its B
Explanation:
B.
Nuclear energy produces little air pollution.
well ... there are sm common things between solutions and colloids
solutions even and fully mixed together and so are colloids
when we let solutions and colloids settle down both of them do not have boundaries ... the particles of colloids and solutions do not settle down
Both are liquids. Both will pass through filters without seperation.
You can see through a solution, as the ions of the solute are dissolved. A colloid is a suspension of insoluble ultra microscopic particles or large molecules in water or other liquid, kept in suspension by Brownian motion.
Answer & Explanation:
The difference between a physical reaction and a chemical reaction is composition. In a chemical reaction, there is a change in the composition of the substances in question; in a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition.
The frequency of the light emitted by the laser pointer is approximately 5.64 x 10ⁱ⁴ Hz, as calculated using the speed of light and the specific wavelength of the light.
To calculate the frequency of the light emitted by the laser pointer, you can use the equation c = fλ, where c represents the speed of light in vacuum (approximately 3.00 × 10⁸ m/s), f is the desired frequency, and λ represents the given wavelength of the light (in this case, 5.32 x 10⁻⁷ m).
By rearranging the equation to solve for frequency (f = c/λ), you can substitute in the given values: f = (3.00 × 10⁸ m/s) / (5.32 x 10⁻⁷ m), which yields a frequency of approximately 5.64 x 10ⁱ⁴ Hz. Therefore, the frequency of the light emitted by the laser pointer is about 5.64 x 10ⁿ⁴ Hz.
It's important to understand that light acts as a wave, and every color of light has a unique frequency, which correlates with its wavelength. The wavelength and frequency of light determine many its characteristics, including the color we perceive.
