Why does the electrical conductivity of ionic compounds change when they are dissolved in water?
Electric current is the flow of charged particles. When ionic crystals disolve in water, the bonds between ions are broken. As a result, the ions are free to move about, and the solution conducts current. Likewise, when an ionic compound melts, the ions are able to move freely, and the liquid conducts current. In contrast, ionic compounds in solid form do not conduct current well. The ions in the solid crystal are tightly bound to each other and cannot move from place to place. If charged particles cannot move, there is no current.
What properties do not change when sugar is dissolved in water?
The property of sweetness of sugar does not change when it is dissolved in water. Although sugar becomes invisible in the solution in water.
Which type of change results in new compounds being formed?
Physical Change
Elements combined to form compounds is a chemical change?
Yes, this a chemical change.
What bacteria in the soil can change nitrogen compounds into?
booty whole (:
How does electric conductivity of ionic compounds change when they are melted or dissolved in water?
Melting or dissolving ionic compounds increases the electrical conductivity. This is because there are free mobile charged ions that can move in the electric field and conduct current.
How does the elctrical conductivity of ionic compounds change when theey are melted or dissolved in water Why is this so?
Electrical conductivity rises dramatically, and this is due to mobile ions that move in solution or the molten salt under the influence of an electrical field. These mobile ions carry the current.
Do the physical properties of water change when a compound is dissolved in water?
no because u can unseparate the 2 compounds

Do the physical properties of water change when a compound is dissolved in water. If so which properties change and why?
The physical properties of water can change when a compound is dissolved in water. The dissolved compound will determine which properties change. Some will change the surface tension, others will change the pH. Many changes are possible.
Is electrical conductivity a chemical change?
Electrical conductivity is a physical property, not a change.
