Question

the best way to ensure that a sanitizing solution remains at the proper strength is? by smelling the sanitizer use sanitizer test strips. to make a large batch each week. to feel how slippery it is. when you calibrate a thermometer, you should place it in a mixture of water and ice and the temperature should be? 0°f 20°f 32°f 41°f

Explanation:

1. Sanitizer test strips are designed to measure the concentration (strength) of sanitizing solutions accurately, while smell, slipperiness, or large weekly batches do not reliably indicate proper strength.
2. The freezing point of water is 32°F, which is the standard reference temperature for calibrating thermometers using an ice-water mixture.

Answer:

1. Use sanitizer test strips.
2. 32°F
