effect stirring solution
Why does stirring increase the rate of dissolution? - CK-12
Stirring increases the rate of dissolution because it helps to distribute the solute particles evenly throughout the solvent. This process enhances the contact between the solute and solvent molecules, leading to more frequent collisions and interactions. As a result, the solute

Comparing the Effects of Stirring Time on Solubility - Nagwa
Let’s have a closer look at how stirring a solution impacts the rate of dissolving the solute. If we stir a solution in an effort to dissolve a solute in a solvent, as was done in the five beakers, we can increase the rate of dissolution by increasing the interactions between solute and solvent

Effect of the stirring speed in the in vitro activity of α-amylase
2021年1月1日 However, the ratio 1047/1022 did not exhibit a clear trend with respect to the stirring speed, which suggests that the retrogradation effect was similar for all stirring speeds. To contrast the results, the starch dispersion was allowed to stabilize for 2 days to achieve a high degree of retrogradation ( Roulet, Macinnes, Gumy, Würsch, 1990 ).

Effect of Variables on pH Measurement in Acid-Rain-Like Solutions
The values for the second main effect, stirring, are about −0.015 pH for solutions 99–1 to 99–5, for the electrodes used in this RT (table 4). Solution 99–6 had such a low strength that stirring caused the results to be very erratic, and hence they were not included in table 4.

Mixing Versus Stirring - Annual Reviews
Mixing is the operation by which a system evolves under stirring from one state of simplicity—the initial segregation of the constituents—to another state of simplicity—their complete uniformity. Between these extremes, patterns emerge, possibly interact, and die sooner or later. This review summarizes recent developments on the problem of mixing in its lamellar representation.
