The scale used for measuring the acidity or basicity of a solution is known as the pH scale. Typically you will see values ranging from 0 to 14, however it is possible to produce highly acidic solutions with a lower pH or a highly basic solution with ahigher pH. A neutral solution has an equivalent concentration of hydronium and hydroxide ions, which has a pH of 7 at 25 °C. A pH less than 7 indicates that a solution is an acid, and a pH greater than / Indicates that a solution is a base.Click on the image below to explore this simulation, which demonstrates the pH scale. The pH of the solution is related to the H₂O¹ ion concentration by the equationpH = -log H₂O¹]When you click the simulation link, you may be asked whether to run, open, or save the file. Choose to run or open itPart DAPHET=In this simulation, allowing you to produce solutions at at 25°C, you should see three modes: Macro, Micro, and Custom. In Macro and Micro, you are provided with a calibrated beaker along with an inlet and an outlet tap. You can choose differentsolutions from the dropdown list above the beaker in the simulation in Macro mode, the pII scale displayed on the left side of the beaker indicates the pII of the solution. In Micro mode, the graphic to the left gives the concentration, or number ofmoles, of H₂O¹, OH, and H₂O.Express your answer numerically to two decimal places.▸ View Available Hint(s)POHShow Transcribed Text■VpH5.80In the simulation, open the Custom made.
