Ph of 3 m hcl
WebTo calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = - log [H3O+]. Example: Find the pH of a 0.0025 M HCl solution. The HCl is a strong acid and is 100% ionized in water. ion concentration is 0.0025 M. Thus: Web2 days ago · pH+pOH =14. pH = 6.98 . HCl Properties. 1. The molar mass of HCl is 36.458 g/mole. 2. Density of 37% HCl is 1.2 g/mL. 3. HCl reacts with metals like Zn, Al, K, etc., to …
