and its corresponding salt (Box ) from the given choices and also select the desired concentrations (Box ) and volume (Box ) of these for the buffer. Step – In order to measure the pH of the made-up buffer click the ‘Insert Probe’ (Box ) on the pH meter. Now the pH meter shows the pH. After measuring you need to remove the probe by clicking ‘Remove Probe” (Box ) to make any changes in the composition.
Step – Now you can vary the concentration and volume of the components and see how the pH changes. By using this tool you can simulate the preparation of a buffer and measure its pH values Please go to the URL tgreenbo/pHbuffer20.html (or) Scan the QR code on the right side
