Answer:
1.0 L
Explanation:
Given data
- Initial volume (V₁): 0.35 L
- Initial concentration (C₁): 2.0 M
- Final concentration (C₂): 0.70 M
John and Alex prepared a diluted solution from a concentrated one. We can find the volume of the diluted solution using the dilution rule.
C₁ × V₁ = C₂ × V₂
V₂ = C₁ × V₁ / C₂
V₂ = 2.0 M × 0.35 L / 0.70 M
V₂ = 1.0 L
Answer:
Heterogeneous mixture solution
Explanation:
The reason this is Heterogeneous is that you cant see each individual compound in the solution. If this was sand or any compund that is not desolvable or not fully desolved in water would be Homogenous since you can see the individual compounds (water and sand)
Well give me the options lol
Answer:
Chlorine bleach is strongly basic. We actually make it by dissolving chlorine gas in a concentrated solution of sodium hydroxide, which forms sodium hypochlorite and sodium chloride, in the following equilibrium.
Explanation:
Answer: The correct option is ALL OF THE ABOVE.
Explanation:
TITRATION is a type of volumetric analysis which is used for determining the concentration of solutions. In this process a specific volume of a solution is placed in a conical flask by means of a pipette and small quantities of a second solution is slowly added from a burette until the end point is reached. This is determined by a means of an indicator which shows a characteristic colour change.
During titration, the following precautions should be followed to avoid errors and maintain standardisation in the experiment.
--> Any air bubble in the burette and pipette must be removed during measurement
--> the burette tap should be tightened to avoid leakage.
--> Remove the funnel from the burette before taking any reading to avoid errors in reading the volume.
--> use the base solution such as Sodium Hydroxide Solution to rinse the burette after washing with soap and tap water:
• to remove any air bubble and fill it's tip
• to remove any residual liquid from the water and soap solution which may interfere with the results of the experiment.
• to check if the burette is in good condition.
Therefore all of the above options to the question are correct.
