What is the word for mixing of particles without stirring?

DIFUSION


What will be effect of mixing on the reaction rate?

Stirring improve the reaction rate.


What can you do to make substances dissolve faster?

Heating the solvent, and mixing (or stirring).


What is the difference between agitation and mixing?

Agitation is the process of keeping a mixture that has been mixed in the proper mixed state required for the 'end' product. Mixing refers to the actual stirring of different liquids and/or materials to blend them together into an end product or mixture. Once this mixture is 'mixed' it may require agitation to keep the mixture in the proper 'mixed' state.


Why should the solution in the polystyrene cup be stirred after each addition of acid?

Stirring the solution in a polystyrene cup after each addition of acid serves several important purposes: Homogeneity: Stirring ensures that the acid is uniformly distributed throughout the solution. This helps in achieving a consistent reaction throughout the entire volume of the solution. Even Reaction: The chemical reaction between the added acid and the solution's components relies on the contact between reactants. Stirring enhances the mixing of reactants, promoting a more even and efficient reaction. Temperature Distribution: The reaction between an acid and a solution can be exothermic, meaning it releases heat. Stirring helps distribute this heat uniformly, preventing localized hotspots that could affect the reaction rate or lead to inaccurate measurements. Accurate Measurements: When conducting experiments, particularly in laboratories, precise control over the reaction is essential. Stirring helps ensure that the reaction progresses consistently, aiding in accurate measurement of the amount of acid added and the resulting changes in the solution. Faster Reaction: Stirring can accelerate the reaction kinetics by increasing the frequency of collisions between reacting molecules. This is crucial for reactions that might be slow or require efficient mixing for optimal results
