What is the PH of a 1.3×(10)^-9 M HBr solution?

Chemistry
1 answer:
olga nikolaevna [1]3 years ago
7 0

pH solution = 8.89

<h3>Further explanation</h3>

Given

The concentration of HBr solution = 1.3 x 10⁻⁹ M

Required

the pH

Solution

HBr = strong acid

General formula for strong acid :

[H⁺]= a . M

a = amount of H⁺

M = molarity of solution

HBr⇒H⁺ + Br⁻⇒ amount of H⁺ = 1 so a=1

Input the value :

[H⁺] = 1 x  1.3 x 10⁻⁹

[H⁺] = 1.3 x 10⁻⁹

pH = - log [H⁺]

pH = 9 - log 1.3

pH = 8.89

If a solution containing 51.429 g of mercury(ii) perchlorate is allowed to react completely with a solution containing 16.642 g
OLga [1]
Hg(No3)2  +NaSO4   --->2NaNO3  +  HgSO4(s)
calculate  the moles  of   each  reactant
moles=mass/molar  mass

moles of  Hg(NO3)2=  51.429g/  324.6  g/mol(molar  mass  of  Hg(NO3)2)=0.158  moles

moles Na2SO4  16.642g/142g/mol=  0.117  moles  of  Na2SO4

Na2SO4  is  the  limiting  reagent in  the   equation   and  by  use  mole  ratio  Na2So4  to  HgSO4  is  1:1   therefore  the  moles  of  HgSO4  =0.117  moles

mass  of  HgSO4=moles  x  molar   mass  of  HgSo4=  0.117 g x  303.6g/mol=  35.5212  grams

If 8.00 mol of NH3 reacted with 14.0 mol of O2, how many moles of H20 will be produced?
otez555 [7]

Answer:

 12 moles of water will be produced

Explanation:

Given data:

Number of moles of NH₃ = 8.00 mol

Number of moles of O₂ = 14.0 mol

Number of moles of H₂O produced = ?

Solution:

Chemical equation:

4NH₃ + 7O₂        →      4NO₂ +6H₂O

Now we will compare the moles of reactant with product.

              NH₃           :           H₂O

               4               :            6

               8               :          6/4×8 = 12

             O₂               :              H₂O

              7                 :               6

              14               :           6/7×14 = 12

 12 moles of water will be produced.
