The hardness of the water is given by the presence of calcium and magnesium <span>carbonates. The mixing of these minerals in water turns the water more alkaline.
</span><span>The Langelier saturation index uses the pH to predict the calcium carbonate stability of water. So, through the pH, it is possible to know whether a water is more or less acidic.</span>
Answer:
Big Bang hypothesis

The basics of the theory are fairly simple. In short, the Big Bang hypothesis states that all of the current and past matter in the Universe came into existence at the same time, roughly 13.8 billion years ago.
