Calcium Carbonate is included in milk
and other sources of dairy products such
as cheese and yogurt.
•
Dissolving calcium carbonate in water is
exothermic, this is because less energy is
required to break the bonds in the
NaHCO3 and CaCl2 molecules than is
released when the CaCO3, NaCl, CO2 and
H2O molecules form.
Chemical property:
calcium carbonate is an odorless
white powder formed by two main
elements: carbon and oxygen.

We can find sodium carbonate in some
types of mineral waters. In addition, large
quantities of this salt are used in forming
glass.
•
When we dissolve sodium carbonate an
exothermic rection occurs, because the
energy required to separate the particles
of sodium carbonate is less than the
energy released by bonding of water
molecules to the particles of sodium
carbonate.
•
Chemical property:
•
Sodium carbonate forms carbonic acid and
sodium hydroxide.

Iron oxide takes in and absorbs heat/energy
from its surroundings, which makes it an
endothermic reaction when dissolved in
water.
•
Chemical property:
•
Iron oxide is a chemical complex which
occurs naturally comprising iron and oxygen.
Magnesium sulfate
(MgSO4)
•
Magnesium sulfate is mainly found in soils,
seawater and mineral springs.
•
When magnesium sulfate is dissolved in
water, energy or heat is released and given
out, which makes this reaction an
exothermic reaction.
Chemical property:
Magnesium sulfate is made up with sulfuric
acid and sodium hydroxide for ph.
adjustment.
Potassium chloride
(KCl)
•
It can be used as a salt replacer, and it can be found In
many other foods including cereals and frozen
entrees.
•
Potassium chloride is endothermic when it's dissolved
in water, that’s because it absorbs heat from its
surroundings which makes it an endothermic
reaction.
Chemical property:
Potassium chloride is a colorless, crystalline appearance
which is unscented.
This article delves into the properties of various chemical substances when dissolved in water, including Calcium Carbonate, Sodium Carbonate, Iron Oxide, Magnesium Sulfate, and Potassium Chloride. It discusses the exothermic and endothermic reactions that occur during dissolution, along with the chemical properties of each substance. Vibrant images provide visual context to enhance understanding.

Testing Chemical Substances (Dissolved Testing Chemical Substances (Dissolved In Water) In Water) By: Tia Karadsheh, Katia Ebaid And Tala Alwazani
Calcium Carbonate is included in milk and other sources of dairy products such as cheese and yogurt. Dissolving calcium carbonate in water is exothermic, this is because less energy is required to break the bonds in the NaHCO3 and CaCl2 molecules than is released when the CaCO3, NaCl, CO2 and H2O molecules form. Calcium Calcium Carbonate Carbonate (CaCO3 (CaCO3) Chemical property: calcium carbonate is an odorless white powder formed by two main elements: carbon and oxygen.
Sodium Carbonate (Na2CO3) Sodium Carbonate (Na2CO3) We can find sodium carbonate in some types of mineral waters. In addition, large quantities of this salt are used in forming glass. When we dissolve sodium carbonate an exothermic rection occurs, because the energy required to separate the particles of sodium carbonate is less than the energy released by bonding of water molecules to the particles of sodium carbonate. Chemical property: Sodium carbonate forms carbonic acid and sodium hydroxide.
Iron Oxide (Fe2O) Iron Oxide (Fe2O) they are used in pigments found in paints, coatings and colored concrete. Iron oxide takes in and absorbs heat/energy from its surroundings, which makes it an endothermic reaction when dissolved in water. Chemical property: Iron oxide is a chemical complex which occurs naturally comprising iron and oxygen.
Magnesium sulfate (MgSO4)
Potassium chloride (KCl) It can be used as a salt replacer, and it can be found In many other foods including cereals and frozen entrees. Potassium chloride is endothermic when it's dissolved in water, that s because it absorbs heat from its surroundings which makes it an endothermic reaction. Chemical property: Potassium chloride is a colorless, crystalline appearance which is unscented.
