Answer:

The first option.

Explanation:

Warm solvent and stirring promote quick dissolving . Also with small crystals more of the surface is in contact with the solvent than with  large crystals.

Answer:  Small crystals of solute are dropped into a warm solvent and then stirred.

Explanation:

Rate of solubility of solids in solvent varies as follows:

Temperature: Increasing the temperature means more solute can be dissolved in the given amount of solvent because the energy of the solute particles increases and more it can interact with the solvent particles. The rate of dissolution of solid also increases in liquids.

Size of the solute particles: If the solute particles is present in smaller size, more it can be dissolved because decreasing the size increases the surface area of the solute particles. Hence, the dissolution increases.

Stirring: This process brings fresh solvent particles to come in contact with the solute particles and hence, fast stirring increases the rate of dissolution.

Thus the solute will dissolve most quickly when small crystals of solute are dropped into a warm solvent and then stirred.

<h3>What is PH?</h3>

PH is a proportion of hydrogen particle focus , a proportion of the causticity or alkalinity of an answer. The pH scale for the most part goes from 0 to 14. Fluid arrangements at 25°C with a pH under 7 are acidic, while those with a pH more prominent than 7 are essential or basic. Having a reasonable pH safeguards our bodies from the back to front. Some even say that illnesses and problems can't fill in a body whose pH is in balance. The pH is a logarithmic scale, that is to say, when an answer becomes multiple times more acidic, its pH diminishes by one. In the event that an answer becomes multiple times more acidic, its pH will diminish by two. The pH scale is recognizable to a bunch of standard arrangements whose pH is laid out by peaceful accord. Essential pH standard qualities are resolved utilizing a fixation cell with transaction, by estimating the possible distinction between a hydrogen terminal and a standard cathode like the silver chloride anode.
