calculate the ph of the resulting solution if 17.0 ml of 0.170 m hcl(aq) is added to 22.0 ml of 0.170 m naoh(aq).
Natalka [10]

The pH of the finsl solution is equal to <u>2.93</u>

Concentration is the abundance of a constituent divided by way of the overall volume of an aggregate. several sorts of mathematical descriptions may be outstanding: mass concentration, molar concentration, variety concentration, and extent awareness.

C₁ = 0.170 m

V₁ = 17 ml = 0.017 L

C₂ = 0.170 M

V₂ = 22 ml = 0.022 L

C₁V₁ =C₂V₂

0.170× 0.017 L = 2.89 × 10⁻³  ------------- HCl

0.170× 0.022 L = 3.74 × 10⁻³  ------------ NaOH

⇒ 3.74 × 10⁻³  -  2.89 × 10⁻³ = 0.85 × 10⁻³

⇒ 3 + log 0.85

⇒ 3 + -0.07

⇒ pH = <u>2.93</u>

The concentration of an solution is a degree of the amount of solute that has been dissolved in a given amount of solvent or solution. A focused solution is one which has a rather huge amount of dissolved solute.

Write the charge balance for a MgSO 4 and NaNO 3 solution that contains H + , OH − , Mg 2 + , HSO − 4 , SO 2 − 4 , MgHSO + 4 , M
irga5000 [103]

Answer :

MgSO_4 solution contains Mg^{2+} and SO_4^{2-}

NaNO_3 solution contains Na^{+} and NO_3^{-}

Explanation :

Ionic compound : It is defined as the compound which is formed when electron gets transferred from one atom to another atom.

All the polyatomic ions always form an ionic compound.

Polyatomic ions : It is a charged species that composed of two or more atoms and these charged species are bonded by the covalent bond.

The given compounds are, MgSO_4 and NaNO_3

MgSO_4 is an ionic compound which is formed by the combination of Mg^{2+} cation and SO_4^{2-} anion.

and,

NaNO_3 is an ionic compound which is formed by the combination of Na^{+} cation and NO_3^{-} anion.

Consider the reaction. At equilibrium, the concentrations are as follows. [NOCl] = 1.4 ´ 10–2 M [NO] = 1.2 ´ 10–3 M [Cl2] = 2.2
EastWind [94]
2NOCl ⇄ 2NO + Cl₂

K = [NO]²[Cl₂]/[NOCl]
K = [0,0012]²[0,0022]/[0,014]²
K = 0,000000003/0,000196
K = 0,000016163
