pH testing strips are readily available indicators used to determine the acidity or alkalinity of a liquid solution. These strips change color based on the pH level of the substance they are exposed to, providing a visual representation of the pH value. For example, dipping a pH strip into a sample of water will reveal whether the water is acidic, neutral, or alkaline based on the resulting color change compared to a reference chart.
The ability to quickly and easily assess pH levels is crucial in numerous applications. These range from ensuring proper water chemistry in aquariums and swimming pools to monitoring soil conditions for optimal plant growth, and even conducting scientific experiments. Historically, pH determination relied on more complex and expensive laboratory equipment, but the development of affordable and convenient pH strips has made this essential measurement accessible to a wider audience.
