Answer 1

The questions are related to devices used in a chemistry lab, such as a hydrometer for measuring the strength of brine, a pipette for small liquid quantities, and a burette for measuring liquids in titrations. Distilled water is used for calibrating refractometers, and bleach is considered a cheap sanitizer.

Step-by-step explanation:

The student is asking about various devices used in a chemistry lab. To answer the questions:

1. A device used to measure the strength of the brine solution is typically a hydrometer, which measures the specific gravity or relative density of liquids. To use a hydrometer, you pour the liquid into a tall container and gently lower the hydrometer until it floats freely, then you record the reading at the surface of the liquid.
2. For measuring the sugar content of sap and syrup, a refractometer is commonly used. This device uses light refraction to determine sugar concentration.
3. To calibrate means to set or determine the accuracy of a measuring device, ensuring precise measurements.
4. When it comes to sanitizers, bleach is often considered the cheapest and most readily available option in the market.
5. A graduated cylinder or burette is used for measuring the volume of liquids accurately, especially in titrations.
6. A pipette is a device used to measure and transfer liquid ingredients in small quantities accurately.
7. The type of water used in calibrating a refractometer is typically distilled water, which provides a known reference point for the measurements.
8. To measure the temperature of fish or food, one would use a food thermometer.
9. A balance or scale is used to measure the weight of objects, such as fish or food, often in a laboratory setting.
10. The number of drops of sap or syrup needed for testing with a refractometer will depend on the device's instructions; generally, a few drops are enough to cover the testing surface.
