Why don't solids and liquids affect equilibrium in a chemical reaction?
Solids and liquids do not affect equilibrium in a chemical reaction because their concentrations remain constant during the reaction. This is because the amount of solid or liquid present does not change as the reaction progresses, so they do not impact the equilibrium concentrations of the reactants and products. Only the concentrations of gases and aqueous solutions can affect the equilibrium of a chemical reaction.
Why do we create a standard curve for a specific chemical when using our spectrophotometer?
A standard curve is created for a specific chemical when using a spectrophotometer to determine the concentration of that chemical in a sample. This curve helps to establish a relationship between the absorbance of the chemical at different concentrations and allows for accurate quantification of the chemical in the sample based on its absorbance readings.
Simple chemistry-based project proposal?
I propose a project to study the effects of different concentrations of a specific chemical on the rate of a chemical reaction. This project can involve preparing solutions with varying concentrations of the chemical, monitoring the reaction kinetics, and analyzing the data to determine the relationship between concentration and reaction rate. The project will provide insights into the role of concentration in chemical reactions and help improve our understanding of reaction kinetics.
What is a dilution series?
A dilution series is a set of solutions where each subsequent solution is made by diluting the previous one with a solvent. This is commonly used in laboratory experiments to create a range of concentrations for testing or analysis.
How do you use ice tables to calculate equilibrium concentrations in a chemical reaction?
To use ice tables to calculate equilibrium concentrations in a chemical reaction, you first write down the initial concentrations of reactants and products. Then, you set up a table to track the changes in concentrations as the reaction proceeds. By using the equilibrium constant expression and the stoichiometry of the reaction, you can calculate the equilibrium concentrations of all species involved.
What is the significance of activity coefficient?
Activity coefficient is significant in thermodynamics and chemical equilibrium calculations because it accounts for deviations from ideal behavior in solutions. It helps to correct the concentrations of species in non-ideal solutions, providing more accurate predictions of properties such as osmotic pressure, vapor pressure, and solubility.

What is a solid that forms from solutions from solutions during a chemical reactions?
precipitate
Why do we need distilled water in preparation of sodium hydroxide solution sodium carbonate and oxalic acid solutions?
Distilled water is required to prevent impurities from affecting the chemical reactions and accuracy of the solutions. Sodium hydroxide, sodium carbonate, and oxalic acid solutions require pure water to ensure precise concentrations and reliable results. Using distilled water helps avoid contamination and ensures the solutions are properly diluted.
What is a fine expensive glassware also the form chemical substances sometimes take for example sugar?
saltine
