What is the concentration of Na ion that remains in solution after the reaction is complete?
The concentration of Na ion that remains in solution after the reaction is complete is determined by the stoichiometry of the reaction and the initial concentration of Na ions.
Suppose you prepare 500 mL of a 0.10 M solution of some salt and then spill some of it What happens to the concencentration of the solution left in the container?
If the spill occurs after solution of the salt is complete, the concentration of the solution left in the container remains unchanged, because by definition of solution, the amounts of solvent and solute spilled will have the same proportions as in the original solution.
What happens to the concentration as the solution is diluted?
As a solution is diluted, the concentration of solute decreases. This is because the amount of solute remains the same while the volume of the solution increases, leading to a lower concentration of the solute in the solution.
Why do solids not affect equilibrium in a chemical reaction?
Solids do not affect equilibrium in a chemical reaction because their concentration remains constant and does not change during the reaction. This means that the presence of solids does not impact the equilibrium position or the rate of the reaction.
What will be the observations when Zinc nitrate solution is added to Barium chloride solution?
A white precipitate of barium nitrate will form, while zinc chloride remains in solution. This reaction results in the formation of a solid called a precipitate, which indicates a chemical reaction has occurred.

What happens to the rate of enzyme concentration when you increase substrate concentration?
The rate of enzyme reaction is increased when the substrate concentration is also increased. However, when it reaches the maximum velocity of reaction, the reaction rate remains constant.
When more solvent is added to a solution what happens to the concentration?
When more solvent is added to a solution, the concentration of the solute decreases. This is because the total volume of the solution increases while the amount of solute remains constant, resulting in a more diluted solution.
How does the concentration of a pure liquid change throughout the course of a reaction?
The concentration of a pure liquid does not change throughout the course of a reaction since it is not involved in the reaction itself. The concentration of a pure liquid remains constant because its molecules do not participate in the reaction.
In a first order chemical reaction the velocity of the reaction is proportional to the while in a zero order reaction the velocity of the reaction is proportional to the .?
In a first-order chemical reaction, the velocity of the reaction is proportional to the concentration of the reactant. In contrast, in a zero-order reaction, the velocity of the reaction is independent of the concentration of the reactant and remains constant over time.
What happens to the concentration as the solution is diluted?
As a solution is diluted, the concentration of solute decreases. This is because the amount of solute remains the same while the volume of the solution increases, leading to a lower concentration of the solute in the solution.
What is the order of a reaction if the graph is curve horizontal?
If the graph of a reaction's concentration versus time is a horizontal curve, it indicates that the concentration of the reactant is not changing over time, suggesting that the reaction has reached completion or is at equilibrium. This typically corresponds to a zero-order reaction, where the rate of reaction is constant and independent of the concentration of the reactants. In such cases, the rate remains constant until the reactants are depleted.
In a reversible reaction two substances are in equilibrium if the concentration of each is doubled but the equilibrium constant remains unaffected?
TRUE
How could you determine whether phenolphthalein remains in the residue of a titration reaction?
The easiest way is to add back some of the solution you were titrating. If phenolphthalein remains, it will react with the solution and change back to purple. Incidentally, phenolphthalein will always remain in the solution of the titration reaction - it changes color depending upon the pH of the solution, but the indicator itself is not affected by the titration reaction.
Why do solids not affect equilibrium in a chemical reaction?
Solids do not affect equilibrium in a chemical reaction because their concentration remains constant and does not change during the reaction. This means that the presence of solids does not impact the equilibrium position or the rate of the reaction.
