1. (1 pts) Milk of magnesia has pH= 10.5. Find concentration of hydronium ions in milk of magnesia.
2. (2 pts) Find pH of solution obtained by dissolving 74 mg of calcium hydroxide in 100.0 mL of water.
2. Milk Measured pH (2 pts) 7.5 a. Determine the concentration of hydronium ions in milk. Show your work. (10 pts) b. Determine the concentration of hydroxide ions in milk. Make sure to use the raw number - not rounded off) from Question 2-a in order to answer this question (otherwise, full credits are not given). Then round off your answer to a correct number of significant figures at the end. Assume that temperature is 25°C. Show your work. (10...
Integrated Problems #13 Milk of magnesia (Mg(OH)2)is often taken to reduce the discomfort associated with acid stomach or heartburn. The recommended dose is 1 teaspoon (5 mL) which contains 4.00 X 10-mg of Mg(OH)2. 1) Magnesium hydroxide is a slightly soluble salt. Write a balanced equilibrium reaction for this process. 2) The Ksp for Magnesium hydroxide is 2.06 X 10-13, what is the pH of the recommended dose of milk of magnesia? 3) If we assume that stomach acid is...
Determine the concentration of hydronium and hydroxide ions in a solution at pH 5.00.
milk of magnesia is a common liquid antacid that contains magnesium hydroxide. since magnesium hydroxide isnt highly soluble in water milk of magnesia is sold as a suspension (thick liquid) where the solute isnt dissolve it stays as a small solid particles homogeneously mixed throughout the liquid; it is estimated that 1.00 ml of milk of magnesia contains 80.0 mg of magnesium hydroxide . assuming that our stomach acid has a concentration of 0.166M HCL how much milk of magnesia...
16. A cup of milk has a pH of 6.40. What is the hydronium-ion concentration? What is the hydroxide-ion concentration? Kw = [H3O+][CH] = 1.0 x 10-14
Find the hydronium ion concentration and pH for the following 1. 2. Calculate the hydronium ion concentration and the pH when 80.0 mL of 0.55 MNH, is mixed with 80.0 mL of 0.55 M HCl (K. = 5.6 x 10-10). Concentration M pH- Phenol (CH-OH), commonly called carbolic acid, is a weak organic acid. C, H, OH(aq) + H2O(0) = CH.0 (aq) +H3O+ (aq) K= 1.3 x 10-10 If you dissolve 0.593 g of the acid in enough water to...
23. Milk of magnesia is often used as an antacid to neutralize acid stomach. It has a hydroxide M (10 pts) ion concentration, [OH]-3.1 x 10 Given K,.-[H'] [0H1-1 x 10'14 pH-log[H Show all your working clearly and include units (i) Calculate [H] for Milk of magnesia
