(2) What is the temperature at density of water is maximum ?
Water is generally a good solvent for ionic compounds. Why?
Water is a polar compound with a high dielectric constant (81).
Hence, it decreases the electrostatic forces of attraction acting between the
oppositely charged ions in an electrovalent compound. Therefore, the ions are
separated and dissolution occurs. Dissolution of electrolytes in water is also
favoured due to hydration of ions.

How many hydrogen bonded water molecules are present?
The maximum number of hydrogen bonds formed by a water molecule in ice is four (4).
Each water molecule can form two hydrogen bonds involving their hydrogen atoms and two further hydrogen bonds formed by the hydrogen atoms attached to adjacent water molecules. These four hydrogen bonds optimally arrange themselves tetrahedrally around each water molecule as found in ordinary ice.

What is "Nascent" Hydrogen ?
Hydrogen
is more receive than dihydrogen at the time of preparation. The Hydrogen
produced in situ in contact with the substance to be reduced is known as
"Nascent" hydrogen.

Why density of water is greater than ice ?
Ice
and water both contains H2O molecules but in water H2O
molecules are more compactly arrange than in ice.
Ice
has a hexagonal cage like structure, inside it H2O
molecules are not closely packed.hence there is more vacant
space between the molecules of ice. As a result the volume
increases due to the vacant spaces. As a result density of ice
decrease.
Other
hand,On increasing temperature then kinetic energy of molecules increases as
result the interaction between the molecules decrease and as a result the the
molecules come closer to each other and the volume decreases, so the density
increases.
The density of water is maximum at 3.98 ℃ approximately 4 degree celsius.

Why ice floats on water at room temperature ?
At
room temperature ice is less dense than liquid water, so it floats on water
surface. The maximum density of water occurs around 3.98 ℃
or approx 4 degrees Celsius.
