Which of the following is/are example(s) of a heterogeneous mixture? a) Colloidal solution b) Suspension c) Solution
(a) and (b)
A colloidal solution and a suspension both have visibly distinct, non-uniformly distributed particles and are therefore heterogeneous mixtures, while a true solution is homogeneous.
Hence, the correct answer is (a) and (b).
If 25 g of salt is dissolved in 175 g of water, what is the concentration of the solution in mass percentage?
Which of the following is a property of a colloidal solution?
Which of the following statements is true for homogeneous mixtures?
What are the two main components of a colloidal solution?
A student mixes oil and water in a beaker and notices two separate layers. Which explanation best fits this observation?
A teacher prepares three mixtures: sugar dissolved in water, salt dissolved in water, and sand stirred in water. Which of the following is a suspension?
Which statement correctly compares the particle size in a suspension with that in a solution?
A chemistry teacher prepares a mixture by dissolving copper sulfate in water until the solution is clear blue. Why is this considered a homogeneous mixture?
What occurs to the particles in the suspension when we shake it?
A student adds salt to water until no more salt dissolves and some salt remains undissolved at the bottom. What does this indicate?
What will happen to the boiling point of water when a little common salt is added to water and then heated?
Which Statement is correct ?
The pH value of 1 × 10 -8 (M) HCl is:
Tyndall effect is not observed in:
A non-volatile solute, urea ($CO(NH_2)_2$, molar mass $60 \ g/mol$), is dissolved in $180 \ g$ of water ($H_2O$, molar mass $18 \ g/mol$). If the vapor pressure of pure water at a certain temperature is $50 \ mmHg$, what is the vapor pressure of the solution when $18 \ g$ of urea is added?
