WebDetermine whether a solution with H3O+ = 7.4 x 10-4 M is acidic, basic, or neutral based on its pH value. Determine whether a solution with H3O+ = 1.7 x 10-8 M is acidic, basic, or … Web24 Mar 2024 · Knowing the dependence of pH on [H3O +], we can summarize as follows: If pH < 7, then the solution is acidic. If pH = 7, then the solution is neutral. If pH > 7, then the solution is basic. This is known as the pH scale. The range of values from 0 to 14 that describes the acidity or basicity of a solution..

13.11: The pH and pOH Scales - Ways to Express Acidity and Basicity
WebA: At 25°C, the pH of a solution is given by: pH = -log [H3O+] Also, At 25°C, the pOH of a solution is… Q: Calculate [H3O+] in a solution that has [OH-] =6.7 X 10-2 M at 25C. Is the solution neutral, acidic,… A: For aqueous solution, the product of the concentration of hydronium and hydroxide ions is given by:… Web(c) [H3O+] = 1.00 x 10¯7M Also, identify each solution as being acidic, basic, or neutral. Solution: (a) The relationship between [H3O+] and [OH¯] is given by: [H3O+] [OH¯] = Kw (7.50 x 10¯5) ([OH¯]) = 1.00 x 10¯14 [OH¯] = 1.33 x 10¯10M Because [H3O+] > [OH¯], this solution is acidic. (b) (1.50 x 10¯9) ([OH¯]) = 1.00 x 10¯14 WebPure water is a neutral substance which means the concentration of hydronium ions, H3O+, is equal to the concentration of hydroxide ions, OH-. Right now, we don't know what those concentrations are, but we know that the concentration of hydronium ions times the … spaceweathere
