Astudent pores 10 g of salt into a container of water and observes the amount of time it takes for the salt to dissolve she then repeat the process using the same amount of salt in water but this time she slowly stirs mixture wall is dissolving the student performs an experiment one more time but this time she started the met mixture rapidly what is the dependent variable in this experiment

The dependent variable is Salt and Water

Because salt is an ionic compound. Namely hydrophilic compounds, meaning compounds that like water.

Water dissolves NaCl by hydrating and stabilizing its ions (Na + and Cl-), weakening the electrostatic interaction between the ions so as to prevent the formation of ionic bonds to form NaCl crystals.

The dissolution process occurs through the replacement of hydrogen bonds between biomolecules with one another by hydrogen bonds between the biomolecules and water so as to prevent electrostatic interactions between biomolecules.
