Question

The answer, in brief, is why is tap water a mixture.

Answer 1

Tap water: Water supplied through the tap and commonly used in various buildings for diverse household purposes like cooking, cleaning, etc. is called tap water.

• This water consists of various minerals like Magnesium$\left(\mathrm{Mg}\right)$, Potassium$\left(\mathrm{K}\right)$ etc. and dissolved salts such as Calcium bicarbonate$\left[\mathrm{Ca}{\left({\mathrm{HCO}}_3\right)}_2\right]$
• It also contains Chlorine $\left(\mathrm{Cl}\right)$ as a disinfectant.
• Like a mixture, tap water contains two or more components (minerals, salts etc.) combined physically but not chemically. So tap water is a mixture.
