SZMahasiswa/Alumni Universitas Negeri Surabaya10 Januari 2023 0845Jawaban yang benar adalah C. 3 Larutan asam merupakan larutan yang jika dilarutkan dalam air menghasilkan ion H⁺. Larutan asam dibagi menjadi asam kuat dan asam lemah. Konsentrasi H⁺ asam kuat dapat ditentukan dengan rumus sebagai berikut. [H⁺] = a × M dimana a = banyaknya ion H⁺ M = molaritas M H₂SO₄ → 2H⁺ + SO₄²⁻ ▪︎menentukan molaritas larutan sebelum pengenceran pH = 2 [H⁺] = 10⁻² M [H⁺] = a × M 10⁻² M = 2 × M M = 5×10⁻³ M ▪︎menentukan molaritas larutan setelah pengenceran M1 × V1 = M2 × V2 M1 = molaritas sebelum pengenceran V1 = volume sebelum pengenceran M2 = molaritas setelah pengenceran V2 = volume total setelah pengenceran M1 × V1 = M2 × V2 5×10⁻³ M × 100 cm³ = M2 × 1000 cm³ M2 = 5×10⁻⁴ M ▪︎menentukan pH setelah pengenceran [H⁺] = a × M [H⁺] = 2 × 5×10⁻⁴ M [H⁺] = 10⁻³ M pH = - log 10⁻³ pH = 3 Jadi, jawaban yang benar adalah akses pembahasan gratismu habisDapatkan akses pembahasan sepuasnya tanpa batas dan bebas iklan!

Sulfuric acid is a strong acid and a dibasic acid. Also, sulfuric acid is a very common acid in laboratories and used in lot of applications. Sulfuric acid solution gives low pH values in aqueous solutions. When concentration of H2SO4 is known in units of mol dm-3, pH value can be calculated easily by pH of sulfuric acidSulfuric acid is a strong acid and completely dissociates to ions in the water. Usually dilute sulfuric acid shows low pH values like HCl acid and HNO3 pH of sulfuric acid onlineYou can enter concentration of sulfuric acid in mol dm-3 in following input box to find pH of the that, in this on-line calculator, we consider both dissociation of sulfuric acid are complete. If you are said that second dissociation is an incomplete one, you cannot use this online dissociation of water is considered as negligible. Therefore no H3O+ ions given by water. Also in very low concentrations of sulfuric acid such as mol dm-3, mol dm-3 are cannot be calculated in this concentration of sulfuric acid in mol dm-3 Calculate pH of sulfuric acidCalculate H+ concentration of sulfuric acidH2SO4 is a dibasic acidSulfuric acid can give two H+ ions. That means, one sulfuric acid molecule can reacts with two hydroxyl → 2H+ + SO42-H+ ions can be expressed as H3O+ to the stoichiometry, concentration of H+ ions is twice as H2SO4 concentration.[H+] = 2 * [H2SO4]Calculate pHSubstitute H+ concentration to the pH = -log10[H+aq]pH of sulfuric acid solutionsWe are going to tabulate pH values of some sulfuric acid solutions with their concentrations. These values are theoretical and may have different from slightly from real of sulfuric acid in mol acidic solution will show lowest pH value? M M M M HNO3In above list, four acids are given. From those acids, HCl, H2SO4 and HNO3 are strong acids and CH3COOH is the only weak acid's pH value decreases when concentration of H+ ions given by the acid increases. Though CH3COOH concentration is high, its pH value is higher because it is a weak acid give a very low H+ ions to water. So CH3COOH can be removed from correct which solution will give higher H+ ion acid gives M H+ ion concentration which is higher than H+ ion concentration of HCl and HNO3 acid solutions. So lowest pH value is shown by H2SO4 acid due to its dibasic is the pH of a M solution of sulfuric acid?For this question, we can give two answers in two methods and they are explained below as case 1 and case 1. We can consider sulfuric acid with complete two dissociationa It means, sulfuric acid release its both H+ ions completely in aqueous solution and the equation is given → 2H+ + SO42-ORCase 2. First dissociation is complete and second dissociation is partial, these equations are given → H+ + HSO4-HSO4- ⇌ H+ + SSO42-How to find pH for these two cases?Case 1 Finding pH for case 1 is easy. Find H+ concentration and substitute it to pH concentration = H2SO4 concentration * 2H+ concentration = * 2H+ concentration = MpH = -log[H+]pH = -log[ = 2 In this case, we think first dissociation is complete and secod dissociation is partial. Due to second dissocation is partial, we assume H+ concentration is given only by first concentration = H2SO4 concentrationH+ concentration = MpH = -log[H+]pH = -log[ = h2so4 solution at ph 2Because you know the pH value, you can calculate the H+ ion concentration. When you know the H+ ion concentration, H2SO4 concentration can be you can find amount and mass of H2SO4 in a certain value. But, you need to know the density of the solution to calculate the mass of solution. When you know the density, you can calculatee thr mass percentage of ph is 50% sulfuric acidIf sulfuric mass fraction is 50%, you can know the concentration of sulfuric acid. But, you need to know the density of the you need to know whether, will concentrated sulfuric acid show strong acid characteristics as the dilute acid. Otherwise we have to consider dissociation constant to calculate pH of 50% sulfuric ph is sulphuric acidUsually dilute sulphuric acid solutions shows very less pH values 1, , If concentrated sulphuric acid solutions are measured, pH may be a negative concentration is sulfuric acid at pH 1?When you know pH, you can calculate concentration of H3O+ ions from pH to pH = 1, H3O+ concentration is mol dm-3. Due to dibasic acid, when sulfuric acid molecule dissociate, two H3O+ ions are given. Therefore, concentration of sulfuric acid should be a half of concentration of H3O+.concentration of sulfuric acid at pH 1 is mol dm-3sulfuric acid ph valueSulfuric acid shows very low pH value. Same concentration sulfuric acid show low pH value than HCl sulfuric acid show low pH value than HCl acid when both have same concentrtion?Sulfuric acid can release two H+ ions. But HCl can release only one H+ ion. So H+ concentration of sulfuric acid is high. So pH value also low in sulfuric acid acid ph of M solutionIF we consider sulfuric acid as a strong acid which dissociates completely to release H+ ions. Therefore, concentration of H+ is M. You can find pH by substituting in pH equation. As the answer, pH = will be of sulfuric acid solution densityTo calculate the density, you need to know mass and volume of the solution. Usually, in commercial sulfuric acid bottles, density is mentioned in the lable. Otherwise you have to measure mass of certain volume of sulfuric acid solution and calculatte the Tutorials to pH of sulfuric acid LarutanK2CO3 1 M sebanyak 100 mL direaksikan dengan 150 mL larutan HCl 2M. hitung volume gas CO2 yang dihasilkan pada keadaan tertentu, di mana volume dari 6,4 gram O2 = 4 L!
