Bookmark or Share- How do you calculate the pH of a solution when given the OH ...The pH + pOH = 14 The pOH = -log[OH-] The pH is measure of acidity of a solution whereas the pOH is a measure of basicity of a solution. The two expressions are opposites expressions. As the pH increases the pOH decreases and vice versa. Both values equal 14. To convert a concentration of into pH or pOH take the -log of molar concentration of the hydrogen ions or the molar concentration of the ...
- What is the [OH^-] in a solution that has a [H_3O]=1.0*10^-6 M ...The answer can be obtained one of two ways: #color(red)("Use the auto-ionization constant of water equation, Kw:"#
- Conjugate Acids and Conjugate Bases - Chemistry - SocraticHCO₃⁻ + H₂O → H₂CO₃ + OH⁻ base + acid → Conj A + Conj B. We see that HCO₃⁻ becomes H₂CO₃. It has one more H atom and one more + charge (-1 + 1 = 0). So H₂CO₃ is the conjugate acid of HCO₃⁻. The H₂O becomes OH⁻. It has one less H atom and one more – charge. So OH⁻ is the conjugate base of H₂O.
- How to you convert between pH, pOH, [H+] and [OH-]? - SocraticHere's a concept map that shows how to get from any of these to the other. [Really, the only things you need to remember are:
- Oxidation Numbers - Chemistry - SocraticOxidation numbers are used to track how many electrons are lost or gained in a chemical reactions. Assigning these numbers involves several rules: Free atoms (H2) usually have an oxidation number of 0, monoatomic ions (Cl-) are usually equal to their charge, and polyatomic ions have several governing principles.
