Definition

in a way driven by positively charged ions (cations) — for instance, when a compound splits into charged fragments or attaches to a surface by electrical pull

Example

Kenji watched as the zinc strip dissolved cationically in the weak acid solution.

verb + cationically: dissolved cationically

The indigo dye bonded cationically to the denim fibres, giving the jeans a deep, lasting blue.

Common collocations
  • cationically bonded
  • cationically dissolved
  • cationically charged
  • cationically modified
Synonyms
  • ionically

    broader — covers both positive and negative ions, not only cations

  • electrolytically

    refers to any process driven by an electric current through a solution, not specifically to cations

Antonyms
  • anionically

    involving negatively charged ions (anions) rather than positive ones

Grammar Patterns

verb + cationically

cationically + past participle

Usage Note

Describes how a substance or process behaves in relation to cations. Distinguish from sense 2, which is specific to cleaning agents and detergents whose active molecule is a cation.

Common Mistakes

The salt dissolved ionicly in the water.
The salt dissolved cationically, releasing positive sodium ions.
'Ionically' covers both positive and negative ions; 'cationically' specifies only positive ions.

2.adverbC2
Definition

by using a cleaning agent whose active molecule is a positively charged ion (a cation); typical of detergents and disinfectants that bind to negatively charged surfaces

Example

Talia bought a kitchen spray that works cationically, dissolving the burnt grease on her stovetop in minutes.

verb + cationically: works cationically

Mei-Lin found the fabric softener acted cationically on her wool jumpers, keeping them soft and static-free.

Common collocations
  • cationically active surfactant
  • cationically formulated
  • cationically modified polymer
Synonyms
  • antiseptically

    refers to killing germs but does not specify the electrical mechanism

Antonyms
  • anionically

    cleaning by means of negatively charged molecules, as in most ordinary soaps

  • nonionically

    cleaning with electrically neutral molecules that do not carry a charge

Grammar Patterns

verb + cationically

cationically + past participle

Usage Note

Specific to cleaning products where the active molecule is a cation (a quaternary ammonium compound, for example). Distinguish from sense 1, which covers general chemical behaviour of cations.

Common Mistakes

The soap cleans anionically because it has a negative charge.
Most soaps clean anionically, but this disinfectant works cationically.
Standard soaps are typically anionic; cationic cleaners are a distinct category often used for disinfection and fabric softening.

Synonym discussion

Sense: adverb/1

These four adverbs all describe how a substance behaves in terms of electrical charge, but they point to different things. 'Cationically' means the process involves positively charged ions — the substance either releases cations or moves as one. 'Ionically' is broader: it covers any charged particle, positive or negative, without specifying which. 'Electrolytically' emphasises that an electric current is driving the chemical change, as in an electrolysis cell; the focus is on the external power source rather than the ion type. 'Anionically' is the direct opposite — it means the process involves negatively charged ions. For example, table salt dissolves cationically (releasing Na⁺) and anionically (releasing Cl⁻) at the same time, so the overall process is ionic. But a piece of zinc dissolving in acid does so cationically, forming Zn²⁺ ions specifically.

Etymology

GreekEnglish

Formed from 'cation' (a word coined by the English scientist Michael Faraday in 1834 from Greek 'kata-' meaning 'down' and 'ion' meaning 'going') plus the adjectival suffix '-ic' and the adverbial suffix '-ally'. Faraday named cations because these positively charged ions move downward — toward the cathode, or negative electrode — during electrolysis.
