Question 2 In a solution, the
is in the greater amount, while the
is in the
lesser amount.

A solution in chemistry is a homogenous mixture of two or more substances.

The substance which is dissolved is called a solute.

The substance in which the solute is dissolved is called a solvent.

It”s not about larger or smaller amount of one another. The solution is a homogenous mixture means that it forms a single phase. You cannot differentiate one substance from another within the solution. Characteristics of a solution are identically distributed through it. For an easy example, if you dissolve sugar in water but some of the sugar is still visibly laying on the bottom of the container (or even floating moved by movement of water) then this not part of a solution - only the dissolved "invisible" sugar is.

You cannot see a solute inside a solvent, nor can you mechanically take one out of another (eg. taking dissolved sugar from water is impossible with a sifter or another mechanical method)

So if the amounts of solute & solvent are equal & it forms a homogeneous mixture it would still be termed Solvent.

Explanation:

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

since electrons are negative the answer is neagtaive
