The H+ ion in the solution is scooped up by these ions, which raises the pH value of the solution. As a result, strong bases commonly have pH values of around 13 or 14. For example – Lithium hydroxide, Sodium hydroxide, Potassium hydroxide, Rubidium hydroxide, Cesium hydroxide, etc. 编...

The electrode may be used to measure the pH of sodium hydroxide solutions with a concentration near 1.0 molar, but it should not be left in this concentration of sodium hydroxide for periods longer than 5 minutes. Using or storing the electrode at very high temperatures (>80°C) or very ...
The most common reason for a consistently high pH level in pools is the use of liquid chlorine or a saltwater system as the primary sanitizer. Sodium hydroxide is produced, which has a pH of around 13. New pool plaster or pebble finishes will also raise pH in pools for about a year aft...

The present invention relates to a no-mix hair relaxer formulation and methods of its use. The relaxer includes a synergistic combination of sodium hydroxide and lithium hydroxide and has a pH of between about 12.7 and about 13.2. These no-mix hair relaxers provide excellent hair straightening ...
pH is defined as a measure of the hydrogen ion activity, an ‘effective concentration’ in an aqueous solution representing the moles of hydrogen ion (H+) per liter of solution for dilute systems at a given temperature. Mathematically, pH and pOH (power of hydroxide ion) are defined as the...
The hydroxides include the familiar alkalies of the laboratory and industrial processes. The hydroxides of the alkali metals, lithium, sodium, potassium, rubidium, and cesium, are the strongest bases and the most stable and most soluble of the hydroxides. Sodium hydroxide, NaOH, also known as ca...
