What are properties of hydrophobic and hydrophilic?
Hydrophobic substances repel water and do not mix well with it due to their non-polar nature, while hydrophilic substances attract and bond with water molecules due to their polar nature. Hydrophobic substances tend to be nonpolar and often include oils and fats, while hydrophilic substances tend to be polar and include salts and sugars.
Which white blood cell type has granules that stain dark purple in response to alkaline dye?
Basophils are the white blood cell type that has granules that stain dark purple in response to an alkaline dye. These granules contain substances such as histamine and heparin, which play a role in inflammatory reactions and allergic responses.
Why are acidic substances lower in pH value than basic substances?
Acidic substances have higher concentrations of hydrogen ions (H+) which results in a lower pH value compared to basic (alkaline) substances. A lower pH value indicates a higher concentration of H+ ions, while a higher pH value indicates a higher concentration of hydroxide ions (OH-) found in basic substances.
Which organisms seem to grow best in alkaline media?
Organisms that commonly thrive in alkaline environments include alkaliphiles, certain species of bacteria such as Bacillus and some types of algae. These organisms have adapted to survive and grow in high pH conditions, which can range from pH 8 to 11 or even higher.
What holds gas in a science lab?
In chemistry, substances are defined as three basic types. Solids, liquids, and gases. Each of these substances contain molecules. So, the difference between these types of substances is the intermolecular forces of attraction between these molecules. Substances with strong intermolecular forces of attraction tend to be solids, and substances with weak I.M.F.A.s are either liquids or gases. The difference between a gas and a liquid is that gas molecules move freely with weak I.M.F.A.s. So, liquid has molecules with stronger I.M.F.A.s, and therefore it retains its shape.
What substances are alkaline?
Substances that are alkaline include sodium bicarbonate (baking soda), ammonia, and some types of soaps and bleach. These substances have a pH higher than 7 and tend to be slippery or caustic to the touch.
What are the differences between basic and alkaline substances?
Basic substances have a pH level above 7, while alkaline substances specifically refer to substances that can neutralize acids. All alkaline substances are basic, but not all basic substances are alkaline.
What is the difference between alkaline and non alkaline?
Alkaline substances have a higher pH level above 7, while non-alkaline substances have a lower pH level below 7. Alkaline substances are often referred to as basic, while non-alkaline substances can be neutral or acidic.
Are corrosive and alkaline both alkaline?
No, corrosive and alkaline are not the same. Alkaline substances have a pH greater than 7, while corrosive substances can cause damage or destruction through chemical reaction. Some corrosive substances can be alkalis, but not all corrosive substances are alkaline.
What are the differences between base and alkaline substances?
Base substances and alkaline substances are often used interchangeably, but there is a subtle difference between the two. Bases are substances that can accept protons, while alkaline substances specifically refer to bases that have a pH greater than 7. In other words, all alkaline substances are bases, but not all bases are necessarily alkaline.
Why are cleaners more alkaline?
Cleaners are more alkaline because alkaline substances are better at breaking down grease, oil, and dirt compared to acidic substances. The high pH of alkaline cleaners allows them to emulsify and lift these types of stains effectively, making them a preferred choice for cleaning tasks that involve heavy soiling.
What is the opposite word of acidic?
The opposite word of acidic is alkaline. Alkaline substances have a higher pH level than acidic substances.
Are Substances that are considered acidic are also called alkaline?
No, substances that are considered acidic are not called alkaline. Acids and alkaline substances are two different categories based on their pH levels. Acids have a pH below 7, while alkaline substances (also known as bases) have a pH above 7.
What is the difference between alkali and alkaline substances?
Alkali substances are bases that dissolve in water, while alkaline substances are compounds that have a pH greater than 7.
What is the difference between alkaline and alkali substances?
Alkaline substances have a pH greater than 7, while alkali substances are specifically bases that can dissolve in water.
What colour does yellow litmus paper turn in alkaline substances?
Yellow litmus paper turns blue in alkaline substances.
What is the substances as alkaline or acidic?
Substances that have a pH level above 7 are considered alkaline or basic, while substances with a pH level below 7 are considered acidic. Examples of alkaline substances include baking soda and soap, while examples of acidic substances include lemon juice and vinegar.
