Final answer:
The pH in a hot tub can be tested using pH test strips or an electronic pH meter.
Step-by-step explanation:
The pH in a hot tub can be tested using various methods:
- One method is to use pH test strips. These strips can be dipped into a water sample from the hot tub, and the color change can be compared to a color chart to determine the pH.
- An electronic pH meter can also be used. A small amount of water from the hot tub can be poured into a container, and the electrode of the pH meter can be submerged into the water to get a pH reading.
