A drug has pKa 5. at which PH it will be 99.9 percent ionized?
To determine at which pH a drug will be 99.9% ionized, we need to consider the Henderson-Hasselbalch equation. The pH at which a drug is 99.9% ionized can be estimated by finding the pH value that is one unit above the pKa of the drug. Therefore, in this case, the drug will be 99.9% ionized at a pH of 6.
When one material turns into a different material with different properties?

When atom is said ionized?
When an atom is ionized, it means that it has gained or lost one or more electrons, resulting in it having a net electric charge. If an atom loses electrons, it becomes positively charged (cation), and if it gains electrons, it becomes negatively charged (anion). Ionization can occur through processes such as exposure to high energy radiation or interaction with other ions.
A mixture that is made when one material is embedded into another material is called?
The mixture is called a composite. This is a material that is made by combining two or more different substances to create a new material with improved properties.
Why different colors appeared by different material?
White light is a mixture of different colors. Different materials have different surface properties; as a result, one material may reflect a larger percentage of red light, and a smaller percentage of other colors, such as blue or green light - thus, it will appear red. Another material may reflect more green light than other colors, so it will appear more green.

what branch of physics deals with ionized gas?
Plasma physics is the branch of physics that deals with ionized gases, often referred to as plasmas. This field studies the behavior of charged particles in these states and their interactions with electromagnetic fields. Plasma physics has a wide range of applications, from astrophysics to nuclear fusion research.

What is is an ionized atom?
When an atom is ionized, that means that it is sharing one or more electrons with another atom.
Liquids can be separate by?
Heating them until they boil and one of them will evaporate before the other depending on their boiling points. Also if one of the liquids is ionised it can be separated by electrolysis where charged graphite rods are placed into the suspension and the ionised substance will be attracted to the opposite charge on the graphits.
Explain why ionized calcium can form absorption lines but ionized hydrogen can not.?
Ionized calcium can form absorption lines because it has multiple energy levels available for electrons to transition between, resulting in absorption at specific wavelengths. In contrast, ionized hydrogen has only one energy level for electrons, making it unable to form absorption lines due to the lack of energy level differences required for absorption.
How many total electrons are present when Chlorine is in its ionized state?
When Chlorine is in its ionized state, it gains one electron to become a chloride ion (Cl-). Therefore, in its ionized state, Chlorine has 18 electrons in total.
The bending of light as it passes from one material to a different material is called?
The bending of light as it passes from one material to a different material is called refraction. This phenomenon occurs due to a change in the speed of light as it travels through different mediums, causing the light rays to change direction at the interface between the two materials.
What is the most abundant interstellar material?
Of the various types of matter that compose the interstellar medium, hydrogen, be it in atomic, molecular, or ionized form (e.g., protons) constitutes the vast majority of the material at over 90%. Helium forms about 9% and less than one tenth of a percent is heavier elements.
What is the chemical formula for the un-ionized form of ammonia?
The chemical formula for un-ionized ammonia is NH3.
When chlorine is ionized does it become anion or cation?
Chlorine becomes an anion when it is ionized, as it gains one electron to achieve a more stable electron configuration.
Can there be doubly ionised hydrogen ion?
No, because neutral hydrogen has only one electron - so it cannot lose TWO.
