What is the typical characteristic of alginate if hot water is used during mixing?

Using hot water during the mixing of alginate can significantly affect its setting time. The correct choice indicates that alginate sets faster when mixed with hot water. This phenomenon occurs because the chemical reaction that takes place when alginate is hydrated is accelerated by higher temperatures. The increased temperature enhances the kinetic energy of the molecules involved, leading to a more rapid mixing and setting process.

When considering the other options, it's important to note that setting more slowly would occur if cold water is used instead, which slows down the reaction. A crumbly consistency could be a result of incorrect mixing or improper water ratios rather than the temperature of the water. Lastly, remaining liquid is characteristic of under mixing or insufficient setting rather than an effect of using hot water. Therefore, the dominant outcome when hot water is utilized is that the alginate mix sets more quickly.
