which of the listed acids are weak acids: Sulfuric acid Hydrosulfuric acid Phosphouric acid Hydrobromic acid Nitric acid Nitrous acid Perchloric acid

strong acid vs weak base

Solution:sulfuric acid = H2SO4The molar mass of H2SO4 = 2×Ar(H) + Ar(S) + 4×Ar(O) = 2×1 + 32 + 4×16 = 98 (g/mol).Suppose that the volume of the solution is...

density D = m / VV = m / DV (HNO3) = 10 / 1.11 = 9 ml

C = 0.16 M n = 0.35 mol. V= c/n. V=0.35/0.16 = 2.22(liters) Answer: 2.22 liters.

Solution: Let x - volume of the concentrated solution (in ml), then: 12.0 ∙ x = 0.369 ∙ 150 Solving: x = (0.369 ∙ 150) / 12.0 = 4.61 ml...

HClO4 + NaOH -> NaClO4 + H2Oc=n/V, then n= c*Vn(NaOH) = 0.0206 L* 0.193 mol/L = 0.00398 molAccording to equation mole ratio n( HClO4):n(NaOH)= 1:1, then n(HClO4)=n(NaOH) = 0.00398 molc=n/V,...

The molarity can be defined as following:M = n / Vwhere M - molarity of the solution, n - number of moles of the solute, V - volume of the...

98% sulphuric acid means in 100 g sulphuric acid source exact amount of sulphuric acid, H2SO4 present 98 g. So in 20 g, exact amount of H2SO4 present =...

Question #137545The density of sulfuric acid is 1.84 grams per cubic centimeters. What is the mass of 75.0cm3 of sulfuric acid?AnswerDensity=mass/volumeMass= Density× volume         = 1.84gcm-3× 75.0cm3         = 138g

Both strong and weak acids are ionized in aqueous solutions, depending on their strength. Strong acids only ionize almost completely in water; hence, nearly all the H+ ions are released.Weak...
