The 129 pages that link to pH, each with the reason it gives.

• Strong acidCompared with: pH describes solution acidity, not the intrinsic strength of the acid present.

• Strong baseRelated: Strong-base pH depends on dissolved amount as well as ionization.

• Weak acidRelated: The hydrogen ions released by a weak acid influence solution pH.

• AmphoterismRelated: Solution pH can influence which acid–base role an amphoteric species takes.

• BasicityCompared with: pH describes a solution’s state, not the intrinsic basicity of a particular species.

• CoagulationRelated: Changing pH alters protein charge and can promote coagulation.

• Fenton reactionRelated: Solution acidity controls iron solubility and strongly affects reaction rates and pathways.

• Hammett acidity functionCompared with: Unlike ordinary pH, H₀ remains useful in highly concentrated and strongly acidic media.

• PreservativeRelated: Acidity can inhibit microbes and determines whether weak-acid preservatives are effective.

• Acid–base chemistryRelated: It expresses solution acidity on a scale tied to proton activity.

• AmylaseRelated: Changes in pH alter amylase activity and stability.

• Baking sodaRelated: Its alkalinity affects flavor, browning, and the acidity of a mixture.

• BioreactorRelated: Bioreactor cultures often require pH regulation to sustain growth and product formation.

• Brønsted–Lowry acidRelated: Proton donation can change hydrogen-ion activity and therefore solution pH.

• Hydrogen ionRelated: pH provides the standard practical scale for describing aqueous acidity.

• Isoelectric pointNarrower topic: The isoelectric point is a particular pH value, not a charge intrinsic to the molecule alone.

• DeprotonationRelated: Solution pH helps determine whether a given acidic group is protonated or deprotonated.

• Food chemistryRelated: Food acidity influences flavor, protein behavior, preservation, and reaction rates.

• Freshwater aquariumRelated: Aquarium pH affects organism health and the toxicity of some dissolved compounds.

• Gold cyanidationRelated: High alkalinity limits the formation and release of volatile hydrogen cyanide during leaching.

• Pourbaix diagramRelated: It is the horizontal coordinate and controls proton-coupled equilibria.

• Sour creamRelated: Sour cream’s low pH reflects fermentation and affects protein structure.

• Acid–base homeostasisNarrower topic: Homeostasis means keeping this measure within a narrow physiological range.

• Brønsted–Lowry baseRelated: It reports solution acidity, not a base's proton-accepting definition.

• Carbonated waterRelated: Carbon dioxide dissolution lowers the pH of carbonated water.

• Common logarithmRelated: It uses common logarithms to compress widely varying acidity levels into a manageable scale.

• Lemon juiceNarrower topic: It expresses the juice’s acidity in a form useful for comparing samples.

• Magnesium hydroxideRelated: Dissolved hydroxide raises solution pH, though limited solubility constrains the effect.

• PepsinRelated: Pepsin’s catalytic activity depends strongly on the stomach’s low pH.

• Sodium benzoateRelated: Lower pH shifts benzoate toward benzoic acid, the form more active against microbes.

• Thermodynamic activityBroader topic: Its definition uses activity rather than hydrogen-ion concentration.

• Water chemistryRelated: It summarizes acidity, which controls many reactions and dissolved forms in water.

• Water disinfectionRelated: Water pH changes chlorine chemistry and therefore its disinfecting strength.

• Acid strengthCompared with: pH describes a solution’s acidity, whereas acid strength describes a particular acid’s proton-donation tendency.

• Arrhenius baseRelated: Adding an Arrhenius base generally lowers hydrogen-ion activity and raises pH.

• Malolactic fermentationRelated: Malate conversion can raise wine pH, affecting microbial and chemical stability.

• Mineral precipitationRelated: pH changes mineral solubility by altering ion speciation and reaction equilibria.

• BetalainRelated: Solution acidity can influence betalain hue and chemical stability.

• Hair dyeRelated: Formulation pH affects hair swelling, cuticle behavior, and dye reactions.

• Lime juiceRelated: Measuring lime juice’s pH quantifies its acidic character.

• PhenolphthaleinRelated: The solution's pH determines which phenolphthalein forms predominate.

• Universal indicatorRelated: The mixture’s color is used to estimate this quantity.

• Wine acidityRelated: It measures wine’s active acidity and affects color, microbial stability, and sulfur-dioxide effectiveness.

• Azelaic acidRelated: Formulation pH affects azelaic acid's ionization, solubility, and skin delivery.

• Fluoroantimonic acidCompared with: Aqueous pH does not meaningfully describe this concentrated, nonaqueous superacid.

• Glycolic acidRelated: A formulation’s pH helps determine how much glycolic acid remains in its un-ionized form.

• pH indicatorNarrower topic: An indicator’s color is interpreted as evidence about this quantity.

• Potassium sorbateRelated: Lower pH shifts sorbate toward sorbic acid, which more readily enters microbial cells.

• Weak baseRelated: Weak-base solutions are characterized by pH values shaped by their limited proton transfer.

• Acidity regulatorRelated: The pH value is the main measure acidity regulators change or stabilize.
