The principle of a pH meter is that it measures the concentration of H+ ions in a solution. If the concentration of H+ ions is equal to the concentration of OH- ions, then the solution is neutral.
pH 1 is the most acidic, as it is closest to 0 on the pH scale. Lower pH values indicate higher acidity.
You can test the pH of a solution using pH strips, pH meters, or pH indicator solutions. With pH strips, you simply dip the strip into the solution and compare the color change to a pH color chart. pH meters provide a digital pH value by immersing the electrode into the solution. pH indicator solutions change color based on the pH of the solution, allowing for a visual estimation of pH.
To measure pH accurately in a solution, you can use a pH meter or pH strips. A pH meter provides a digital reading of the pH level, while pH strips change color based on the pH level of the solution. Simply dip the pH meter probe or pH strip into the solution and read the pH value indicated.
pH 0 < acidic < pH 7 neutral = pH 7 pH 7 < basic < pH 14
The lower the pH, the more acidic the solution is. Remember, pH 7.0 is H2O. As pH decreases below 7, the solution's acidity increases. As pH increase above 7, the basicity of the solution increases. Hence, in the choices you provided, pH 1.0 is most acidic.
Three important principles of sampling survey are: 1. Principle of validity 2. Princilpe of statistical regularity 3. Principle of optimization
First, measure the mass of the water in the bathtub using a scale. Next, immerse yourself completely in the water and measure the increase in water level using a measuring cup. This increase in volume of water displaced is equal to your body volume. Finally, apply Archimedes' principle which states that the buoyant force acting on an object is equal to the weight of the water displaced, to calculate your mass.

The pH is determined with a pH-meter.
pH 0 < acidic < pH 7 neutral = pH 7 pH 7 < basic < pH 14
pH = 14 is basic pH = 7 is neutral pH - 1 and 2 are acidic; pH = 1 is more acidic than pH = 2 Therefore a solution at pH 1 has higher concentration of H+ than at pH 14
The lower the pH, the more acidic the solution is. Remember, pH 7.0 is H2O. As pH decreases below 7, the solution's acidity increases. As pH increase above 7, the basicity of the solution increases. Hence, in the choices you provided, pH 1.0 is most acidic.
Most acidic is substance of pH of 2, then of pH of 5 and the substance of pH 7 is neutral and the substance of pH 11 is basic
