5. Determine the hydronium ion concentration and hydroxide ion concentration in each solution. a) 0.95 mol/L hydrobromic acid. b) 0.012 mol/L calcium hydroxide 6. Morphine, C₁7H19NOs, is a naturally occurring base that is used to control pain. A 4.5 x 10-3 mol/L solution has a pH of 9.93. Calculate Kb for morphine.

In your kitchen, you have a vinegar bottle that indicates that it has 5% vinegar. As you wanted to see if this claim is true. You decided to do a quantitative analysis u Let's assume that you are performing an experiment in a laboratory and have all for this titration. You have collected following information. Volume of the acetic acid (CH3COOH)use for the titration = 25.0 mL Morlarity of the NaOH solution = 0.90 M Initial burette reading = 22.82 mL Final burette reading = 45.67 ml Assume density of the vinegar solution is same as the density of water (1.0g/mL) Using above information how do you prove or discard above claim (5% vinegar).

Please send me the question in 20 minutes it's very urgent plz

The answer is 250mL and I am not understanding how. Please explain

I gave the wrong molarity when I submitted this last. I used 25 ml of HCl. The molarity of NaOH is 0.1065 instead of what I have in the image. Sorry again,but thank you!

Calculate the volume of a 1.420MNaOH solution required to titrate 23.50mL  of a 1.500MH3PO4 solution. Round your answer to 4 significant digits.
