If you mix 10 ml of a 0.1 m hcl solution with 8 ml of
a0.2 m naoh solution, what will be the resulting ph?

The  pH of the resulting solution is 12.52.

Explanation:

n = number of moles

V = volume of the solution in Liters

1)1 mol of HCl gives 1 mol of hydrogen ion.

Concentration of the hydrogen ion = 0.1 M

Volume of the solution = 10 mL = 0.010 L

Moles of hydrogen ions =  = 0.001 mol

2) 1 mol of NaOH gives 1 mol of hydroxide ion.

Concentration of the Hydroxide ions = 0.2 M

Volume of the solution ,V'= 8 mL = 0.008 L

Moles of hydroxide ions ,n ' = 0.0016

1 mol of HCl neutralizes 1 mol of NaOH ,then 0.001 mol of HCl will neutralize 0.001 mol NaOH.

So left over moles of hydroxide ions in the solution will effect the pH of the solution:

Left over moles of hydroxide ions in the solution = 0.0016 mol - 0.0010 mol = 0.0006 mol

Left over concentration of hydroxide ions:

pH +pOH = 14

pH = 14 - 1.48 = 12.52

The  pH of the resulting solution is 12.52.

where's the diagram?

they are made of gases.

they have a spherical shape.

they make energy through fusion.
