- Q3. This question is about the pH of several solutions. Give all values of pH to 2 decimal places. (a) (i) Write an expression for pH. (b) (ii) Calculate the pH of the solution formed when 10.0 cm³ of 0.154 mol dm-³ hydrochloric acid are added to 990 cm³ of water. The acid dissociation constant, Ka, for the weak acid HX has the value 4.83 x 10-5 mol dm-³ at 25 °C. A solution of HX has a pH of 2.48 Calculate the concentration of HX in the solution. Page 4 of 14arrow_forwardis it acidic, basic, or neutral?arrow_forwardA scientist is comparing two lakes. She finds that water samples from Lake X have a pH of 3.50 and water samples from Lake Y have a pH of 5.50. Therefore, it can be said that Lake X has a hydronium ion concentration that is times greater than Lake Y.arrow_forward
- 4.00 g KOH was added to the less basic solution in number 3. What will be the resulting pH of the solution? (MM KOH=56) 3. 5.00 g NaOH and 5.00 g Ba(OH)2 were used to prepare 1L solution each. Which solution will be more basic? (MM NaOH=40, Ba(OH)2=171.3)arrow_forwardThe pHpH scale for acidity is defined by pH=−log[H+]pH=-log[H+] where [H+][H+] is the concentration of hydrogen ions measured in moles per liter (mol/L). (A) If there are 0.0079432823472428 mol/L of hydrogen ions in a certain substance, what is the pH of this substance?pH=pH= Round your answer to at least two decimal places.

- What is Ka for the conjugate acid of NH₃ (Kb = 1.8 × 10⁻⁵)?arrow_forwardDetermine the pH of each of the following solutions. Ka and Kb values are given in the following table: Hydrazine (H2NNH2 ) Kb=1.3×10−6 Hydroxylamine ( HONH2 ) Ka=1.1×10−8 0.0084 M hydrazine 0.168 M hydroxylaminearrow_forwardA 0.21-mol sample of a diprotic acid, H2A, is dissolved in 250 mL of water. The Ka1 of this acid is 1.0 × 10–5 and Ka2 is 1.0 × 10–10. Calculate the concentration of A2– in this solution. 1) 1.0 × 10–5 M 2) 1.4 × 10–3 M 3) 2.9 × 10–3 M 4) 1.0 × 10–10 M 5) 0.84 Marrow_forward
- You are told that a heavily polluted sewer contains high concentrations of H2S (pKa₁ = 7.2) and ammonia (pKa = 9.3). Upon inspect of the manhole at the sewage treatment plant you can smell ammonia (NH3) but cannot detect any H2S odor. What can you say about the likely pH range of the sewage?arrow_forwardBe sure to answer all parts. A 0.025 M solution of a weak acid (HA) has a pH of 4.28. What is the K, of the acid? Ка x 10 (Enter your answer in scientific notation.)arrow_forwardCalculate the pH of each solution. A solution containing 0.0289 M maleic acid and 0.040 M disodium maleate. The K, values for maleic acid are 1.20 x 10-2 (Kal) and 5.37 x 10-7 (Ka2). pH = 6.059 Incorrect A solution containing 0.0262 M succinic acid and 0.015 M potassium hydrogen succinate.
