What is the ph of a solution that contains 1.2 moles of nitric acid (hno3) and 1.7 moles of hydrochloric acid (hcl) dissolved in 1000 liters of water?

 [H+]= 1.2 + 1.7/1000=0.0029 M
pH = - log 0.0029=2.54 

moles HCl = 0.0025 L x 6.0 M=0.015 
[H+]= 0.015/ 1.75=0.0086 M 
pH = 2.1  so the ph is 2.1 of given solution

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
