A pH meter would give the most precise result.
A graduated cylinder
The scientist should use pH indicator paper or pH test strips, which are designed to provide a quick visual assessment of pH levels. These tools change color depending on the acidity or alkalinity of the solution, allowing for an easy comparison against a provided color chart to determine the approximate pH. Alternatively, a pH meter could be used for more precise measurements, but it requires calibration and is not entirely visual.
pH is a measure of the hydrogen ion (H+) activity in a solution.
We can use a pH paper.
The pH of solutions (liquids) is measured.
A pH meter
A pH meter
It is a simple and not expensive tool to measure pH.
The scientist should use a pH meter to measure the precise pH of the solution. This device provides an accurate numerical value for the acidity or alkalinity of the solution.
You should use a pH meter or pH paper to measure the acidity of a solution. These tools provide a way to quantitatively determine the concentration of hydrogen ions in the solution, which correlates with its acidity.
The scientist can use litmus paper or pH test strips to measure the approximate pH of swamp water. These tools are simple, inexpensive, and easy to use for a quick estimation of the water's acidity or alkalinity.
A scientist should use a pH meter to determine the pH of a solution. This device accurately measures the hydrogen ion concentration in the solution and provides an immediate reading of the pH level.

To measure the pH of a river, you can use a pH meter or pH test strips. Collect a water sample from the river and follow the instructions provided with the pH meter or test strips to obtain a pH reading. Remember to calibrate your pH meter before taking measurements.
