WebThe pH scale is a convenient way to represent the acidity or basicity of a solution. We can calculate the pH of a solution by taking the negative logarithm of the hydronium ion concentration, or pH = -log[H₃O⁺]. At 25°C, a solution with pH < 7 is acidic, a solution with pH > 7 is basic, and a solution with pH = 7 is neutral. Created by Jay.

WebSlag basicity is defined as the (CaO% + MgO%)/SiO 2 % ratio of the liquid. If this ratio exceeds 1, the slag is basic; if it is less than 1, it is acidic. Basic slags can be obtained by charging the cupola with sufficient fluxes (limestone and dolomite) to ensure the required Ca and Mg content. WebThe basicity of alcohol is accredited to the presence of lone pairs of electrons available for donation on the O-H bonded oxygen atom. Lewis bases are electron pair donors. Ethers: Ethers (R-O-R) exist as sweet-smelling, colorless liquids at r.t.p. Ethers are slightly polar molecules, owing to a polar C-O-C linkage.
