The acidity of the soil. Some plants like more acidic soil while others prefer more alkaline. By measuring the pH, you are able to adjust the soil's acidity accordingly.
We can use a pH paper.
measure the pH of a liquid and possibly a solid
You can measure the pH of an unknown liquid using a pH meter or pH test strips. Simply dip the pH meter or test strip into the liquid and observe the reading or color change, respectively. This will give you an indication of the pH level of the unknown liquid.
pH paper and pH meter
With a Ph meter.
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.
Using a pH-meter the measurement is more accurate and sure.
If you think to pH, measure this value with pH paper or with a pH-meter.
using a pH meter.
Using a pH-meter the measurement is more accurate and sure.But at home you can use a pH-paper for transparent liquids.
This instrument is called pH-meter.
pH effectively measures how many hydrogen ions there are in volume of water. A pH meter uses litmus paper to measure the ions.
