What is the pH of a 1.0 x 10^-4 M solution of sulfuric acid (H2SO4)?

Marizza181 [45]

Hello!

datos: Molarity = $1.0*10^{-4}\:M\:(mol/L)$

ps: The ionization constant of the sulfuric acid is strong and completely dissociates in water, so the pH will be:

$pH = - log\:[H_3O^+]$

$pH = - log\:[1*10^{-4}]$

$pH = 4 - log\:1$

$pH = 4 - 0$

$\boxed{\boxed{pH = 4}}\end{array}}\qquad\checkmark$

Note:. The pH <7, then we have an acidic solution.

I Hope this helps, greetings ... DexteR!

Solid lithium chloride decomposes into chlorine gas and solid lithium. Write a balanced equation.

quester [9]

Lithium chloride is LiCl (because the valence of lithium is +1 and the valence of chlorine is -1). So the chemical equation is: Li Cl(s) ----> Li(s) + Cl2 (g). To balance the equation you need to multilply both Li Cl (s) and Li(s) by two, and then you finally get the balanced equation: 2 LiCl ---> 2 Li(s) + Cl2(g). Note that the number 2 to the right of Cl is a subscript.

A 4.55 l sample of water contains 0.115 g of sodium ions. determine the concentration of sodium ions in ppm if the density of th

Slav-nsk [51]

When one talks about ppm in a liquid solution someone means mg/L so we would not be using the density. This usually means ug/g or mg/kg 0.115 g Na^+ * 10^6 ug/1 g = 115000 ug/g 4.55 L * 1000 mL/1L = 4550 mL Concentration of Na^+ in ppm: 115000 ug/g /4550 mL = 25.27 pm of sodium ion

2.50g of a certain Compound X, known to be made of carbon, hydrogen and perhaps oxygen, and to have a molecular molar mass of 12

Art [367]

Answer:

Molecular Formula = C₁₀H₈

Explanation:

Step 1: Calculating Moles for each Element:

C = Mass of CO₂ × (1 mol of CO₂÷ M.Mass of CO₂) × (1 mol of C ÷ 1 mol of CO₂)

C = 8.60 g × (1 mol of CO₂÷ 44.011 g.mol⁻¹) × (1 mol of C ÷ 1 mol of CO₂)

C = 0.1954 mol

H = Mass of H₂O × (1 mol of H₂O ÷ M.Mass of H₂O) × (2 mol of H ÷ 1 mol of H₂O)

H = 1.41 g × (1 mol of H₂O ÷ 18.106 g.mol⁻¹) × (2 mol of H ÷ 1 mol of H₂O)

H = 0.1557 mol

Step 2: Calculate the Smallest whole number ratio as,

C H

0.1954 0.1557

0.1954/0.1557 0.1557/0.1557

1.25 1

Multiply ratio by 4,

5 4

Result:

Empirical Formula of Propane is C₅H₄

Step 3: Calculate Molecular Formula:

Molecular formula is calculated by using following formula,

Molecular Formula = n × Empirical Formula ---- (1)

Also, n is given as,

n = Molecular Weight / Empirical Formula Weight

Molecular Weight = 128.0 g.mol⁻¹

Empirical Formula Weight = 5 (C) + 4 (H) = 64 g.mol⁻¹

So,

n = 128.0 g.mol⁻¹ ÷ 64 g.mol⁻¹

n = 2

Putting Empirical Formula and value of "n" in equation 1,

Molecular Formula = 2 × C₅H₄

Molecular Formula = C₁₀H₈
