Which of the following statements represents the basic principle of operation of an electrical salinity indicator?

Question 1 of 27070

Which of the following statements represents the basic principle of operation of an electrical salinity indicator?

🔍 Key Concepts

• Salinity is related to the amount of dissolved salts (ions) in water • More dissolved salts (ions) change how well water carries electric current • Relationship between resistance and conductivity in an electrical circuit

💭 Think About

• If water has more salt in it, what happens to its ability to conduct electricity—does current flow more easily or less easily? • Which choice describes a method that directly relates to how easily electric current passes through the water sample? • Which options are talking about salt content versus things like acidity (pH) or oxygen content?

✅ Before You Answer

• Eliminate any choices that deal with hydrogen ion concentration (pH) rather than salt content • Eliminate any choices that focus on dissolved oxygen instead of dissolved salts/ions • Focus on the option that is clearly tied to how the water’s electrical properties change with ion (salt) concentration
