To see if I am on the right track
First write the balanced reaction
2HCl + Mg(OH)2-----------------> MgCl2 + 2HOH
Moles of HCl
Conversion 200ml= 0.2L
=0.2L * 0.150mole/L
= 0.03 moles
Moles of Mg(OH)2
Conversion 125 ml= 0.125L
=0.125L * 0.175mole/L
= 0.021875 moles
Since HCl moles is greater than that of Mg(OH)2(0.021875moles) therefore, HCl is aciditic. |
