Salts are ionic in nature due to the presence of ions. They are brittle, hard and crystalline solids. Salt is
white, odorless
and it has a salty taste. All potassium (K), ammonium (NH
4
+) and sodium (Na) salts are soluble in water (H
2
O).
What are the chemical properties of salts?
- Crystals or white crystalline powder.
- Transparent and colourless in crystalline form – rather like ice.
- Crystallises in the isometric system, usually in the form of cubes.
- Soluble in water (35.6g/100g at 0°C and 39.2g/100g at 100°).
What description of salt is a physical property?
Salt is
dull and brittle and conducts electricity when it has been dissolved into water
, which it does quite easily. Physical properties of matter include color, hardness, malleability, solubility, electrical conductivity, density, freezing points, melting points, and boiling points.
What are the physical and chemical properties of salt and sugar?
Salt and sugar may look the same, but they obviously taste very different. They are also very different chemically. Salt is made up of sodium and chloride and is ionically bonded. Sugar, on the other hand, is
composed of carbon, oxygen, and hydrogen and has covalent bonds
.
What is physical properties and chemical properties?
A physical property is
a characteristic of a substance that can be observed or measured without changing the identity of the substance
. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.

What are two physical properties of salt water?
The physical properties of seawater include both ‘thermodynamic properties' like
density and freezing point
, as well as ‘transport properties' like the electrical conductivity and viscosity.
What are physical properties of vinegar?
Physical properties: Vinegar is
a colorless liquid with corrosive pungent vinegar-like odor with a sour taste
. Its density is 1.05 g/mL, and its melting and boiling point are 16 oC and 118 °C, respectively. It is highly miscible in water, methanol and ethanol.
What are the physical properties?
A physical property is
a characteristic of matter that is not associated with a change in its chemical composition
. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.
Why salt and sugar have similar physical properties?
Salt and sugar share many properties.
Both are crystalline in structure
, in some forms are colorless and odorless and both are flavor enhancers. Both have antimicrobial properties that have been recognized as effective in the treatment of wounds and illnesses and the preservation of foods since ancient times.
Is gasoline a chemical property?
Gasoline is a refined product of
petroleum
consisting of a mixture of hydrocarbons, additives, and blending agents. … Information regarding the chemical identity of gasoline is located in Table 3-l.
What's the chemical formula of sugar?
It is a disaccharide, a molecule composed of two monosaccharides: glucose and fructose. Sucrose is produced naturally in plants, from which table sugar is refined. It has the molecular formula
C12H22O11
.
What is Class 9 chemical property?
Chemical properties are
