WebThe ion-product constant is KW = 1.0 × 10 -14 the whole time at 25°C. In pure water, [H 3 O +] = [OH –] = 1.0 × 10 -7. When we increase [H 3 O + ], like a seesaw, this is balanced and counteracted by a decrease in [OH –] – this keeps KW constant. Check Your Learning 5.2.2 – The Inverse Proportionality of [H3O+] and [OH−] WebThe value of Kw Like any other equilibrium constant, the value of K w varies with temperature. Its value is usually taken to be 1.00 x 10 -14 mol 2 dm -6 at room temperature. In fact, this is its value at a bit less than 25°C. The units of Kw: K w is found by multiplying two concentration terms together. Each of these has the units of mol dm -3. granby memorial high school ct
