Ion-selective electrodes are used to measure it.
One equation named after Hammett can calculate an alternative to this quantity if the Henderson- Hasselbalch equation does not apply, and changes in this quantity resulting from temperature can be modeled using the Nernst equation. Ion-selective electrodes are used to measure it. Ketosis can lead to rapid drops of this quantity in the blood, in which this has a value of about 7.2. This quantity can be obtained by taking the negative base-ten logarithm of hydronium ion concentration. For 10 points, identify this chemical quantity that measures how acidic or basic a solution is and is equal to 7 for water.
