What Electrolytes Are And How They Work

Svante Arrhenius took his first breath in Vic Castle, Sweden in 1859. By the age of three, he had taught himself to read without assistance from his parents. He soon became an arithmetical prodigy after watching his father, a surveyor perform calculations. In 1884, he suggested that solid, crystalline salts disassociate into paired, charged particles when they dissolve. This was the first, tentative step to finding out what electrolytes are, how they work, and what they do.

Michael Faraday, born in England in 1791 was the father of electromagnetism, and electrochemistry. Decades before Arrhenius took his bold step forward, Faraday had already invented the name “ions” for charged particles. He believed they formed during the process he called electrolysis. However, Arrhenius did not think the presence of an electric current was necessary for the crystalline salts to separate.

Our Modern Understanding of What Electrolytes Are

Chemists believe we now know exactly how electrolytes work, and what electrolytes are. They form when we add a salt to a solvent such as water, causing the components to separate. The number of ions produced depends on the saturation of the solution.  This is why we regularly top up the water in unsealed lead-acid batteries to maintain the optimum balance.

Are Electrolytes the Source of All Life?

That is a deep, deep question and we will not attempt an answer here. We do know that all life forms require a subtle, but complex electrolyte balance between the environments inside, and outside their cells. These gradients manage our body hydration, nerve and muscle function, and the acidity level of our blood. If we dehydrate and need a top up, then fruit juice, milk, nuts, potatoes, and avocados are all naturally electrolyte-rich.

About Author


I tripped over a shrinking bank balance and fell into the writing gig unintentionally. This was after I escaped the corporate world and searched in vain for ways to become rich on the internet by doing nothing. Despite the fact that writing is no recipe for wealth, I rather enjoy it. I will not deny I am obsessed with it when I have the time. My base is Umtentweni in South Africa on the Kwazulu-Natal South Coast (30.7167° S, 30.4667° E). I work from home where I ponder on the future of the planet, and what lies beyond in the great hereafter. Sometimes I step out of my computer into the silent riverine forests, and empty golden beaches for which the area is renowned.
