@ Smokefoot:, are you sure in changing "product of the concentrations" to "sum of the concentrations" here? The product of the concentrations/(or to be more correct, activities) would remain constant as K_w.. Galobtter ( pingó mió) 17:56, 9 August 2018 (UTC) reply

explain Hard water and soft water and how to reduce the hardness — Preceding unsigned comment added by 49.206.5.28 ( talk) 12:34, 20 March 2019 (UTC) reply

Because it is such a huge topic, we have lots of articles about water. This article is about certain technical properties of water. As the Hatnote says: see Water for a more general discussion. That article will take you to Water hardness. - Arch dude ( talk) 16:17, 28 June 2019 (UTC) reply

This article has been thoroughly written. The lead section lays the foundation for the rest of the article, explaining the basics of water. The article does a great job building upon information to create a cohesive explanation of water and its many qualities. The article also references many different sources.

In every point of the phase diagram in section "Triple point" there is a certain quotient "actual molar volume of water / (theoretic or actual) molar volume of vapour water". In the orange coloured vapour area this would be everywhere 100%, molar volume there is simply R × T / p, while in the liquid and solid areas certain distinct percentage lines result which should also be a bit visible? -- LKreissig ( talk) 17:03, 16 May 2022 (UTC) reply
