WebThe pH scale is logarithmic and shows the solution’s concentration of hydrogen ions inversely. More specifically, the pH of the solution is the negative logarithm to the base 10 of its hydrogen ion concentration in moles per litre. The pH scale can be traced to a series of standard solutions whose pH is defined by international agreement. WebWhen you are given the molarity of an acid solution, and asked to determine the pH, a molarity greater than 1 produces a negative pH. Is this possible? Barry Bosco It's …

WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. … WebMar 23, 2024 · The pH is thus –log (0.100) = 1.000. The formula for pH is pH = -log [H+]. This means pH is the negative base 10 logarithm (“log” on a calculator) of the hydrogen ion concentration of a solution. To calculate it, take the log of the hydrogen ion concentration and reverse the sign to get the answer. impact factor of tetrahedron letters

WebThe pH scale is a convenient way to represent the acidity or basicity of a solution. We can calculate the pH of a solution by taking the negative logarithm of the hydronium ion concentration, or pH = -log[H₃O⁺]. At 25°C, a solution with pH < 7 is acidic, a solution with pH > 7 is basic, and a solution with pH = 7 is neutral. Created by Jay.

WebYes, it is possible for a solution to have a negative pH, but it has to be a relatively concentrated solution of a strong acid. False, because it is possible but only if the concentration of the weak acid is much higher, then even though it only dissociates partially, it produces more H+ ions than the strong acid, leading to a lower pH. WebThat gives us pH plus 4.75 is equal to 14.00. And solving for the pH, we get that the pH is equal to 9.25. So we have the pH and our goal is to solve for the concentration of hydronium ions, and pH is equal to the negative log of the concentration of hydronium ions. So we can plug our pH right into this equation.

WebMar 14, 2024 · Although most solutions have a pH or pOH in the range from 0-14, it is possible to have a negative pH or negative pOH. This is because pH=-log [H3O+]. WHen [H3O+] is a value greater than 1, such as the example of 1.5M you provided, then the equation produces a negative value. This just means that the solution is extremely … WebIf the molarity of hydrogen ions is greater than 1, you'll have a negative value of pH.
