NaCl (Salt)

What Bond occurs between Na+ and Cl- to make Salt

• Covalent

• Ionic

• Metallic

• Non Polar

Answer explanation

since the Electronegativity

of the ions is greater than 1.8 it creates a ionic bond with each ion having a slight + or -

What Is the Melting Point of NaCl (Salt)

• 801C

• 1074.15K

• 500C

• -273C

Answer explanation

Since Ionic Bonds are quite strong the melting point of the Compound will be quite high.

What Is its Molecular Structure Like

• Na Attached to Cl in a cube like formation

• Na And Cl ions floating around

• Na And Cl Combined in a circular Shape

On the Moh Scale of hardness What is Salt (Diamond is a 10 for reference and Gold is a 2.5)

• 2

• 5

• 6.7

• 8

Answer explanation

Salt is a 2 in the Moh scale and comparing to something like diamond wich is a 10 and really hard so salt is more like a softer material in a sense

Whats Salts Luster Like

• Salt Is Like Glass in appearance and Physical Properties

• Dull

• Salt Is Like metal in appearance and Physical Properties

Answer explanation

Salts luster is vitreous meaning its appearance is almost like glass andits physical properties are also similar

Tensile strength of NaCl MPA (pounds of force per square inc)

• 14.22mpa

• 210mpa

• 1.65mpa

Answer explanation

So for salt it's 1.65 mpa but to explain that better its the amount of force in the unit of pounds per square inch of material so for salt it's max is 1.65 pounds of force per square inch before it fails so comparing to copper something with 210 mpa it is alot more fragile then a metal such as copper

the Solubility of salt

• Will dissolve in water and break up into its ions

• Wont dissolve in water and Wont break up into its ions

• It Just sits there

Answer explanation

NaCl will dissolve in water (H2O) and will break apart into its ions of Na+ and Cl-

Salt Has an Odour

• True

• False

Answer explanation

Salt has No Apparent Odor

What Colour Does a Flame Turn after Salt is added

• Yellow

• Red

• Green

• Blue

Answer explanation

The Colour of the flame helps to determine the temperature of the flame so when the flame test is applied to salt it emits a yellow Colour which is around 1700 C well above the melting and boiling point of salt

Does Salt react With Acids

• Yes

• No
