Which best describes the pH scale?
Answer: The correct answer is Acids measure below 7. pH ( Potential of hydrogen) is used to measure the basicity ( alkalinity) or acidity of water soluble substances. The value on pH scales lies from 0 to 14 where 7 indicates a neutral pH that corresponding to neutral solutions like water.
What is least likely to dissolve completely in water?
hydrochloric acid sulfuric acid nitric acid acetic acid.
Which product contains a strong base that would most likely completely dissolve in water Brainly?
Answer: A drain cleaner is a base and thus it gets dissolved in water to produce a liquid which has density higher than the water. Explanation: ^^ hope this helped !!
Which product contains a strong base?
A strong base is something like sodium hydroxide or potassium hydroxide which is fully ionic. You can think of the compound as being 100% split up into metal ions and hydroxide ions in solution. Each mole of sodium hydroxide dissolves to give a mole of hydroxide ions in solution.
Which would increase the rate of dissolving salt into water?
Explanation: Crushing or grinding increases the surface area of the salt that is exposed to the molecules of water. Stirring increases the speed at which the particles of salt come in contact with the water molecules.
Which solution is the most concentrated?
Explanation: A concentrated solution will contain the most solute molecules per solvent molecules. Hence, option D) is most concentrated….Which solution is most concentrated?
| A) Br | B) Cl |
|---|---|
| C) I | D) F |
Which solution is the most concentrated 2.0 mL?
- Answer: the option 4) 2.0 mL of 10.5 M H₂O₂, where H₂O₂ has a molar mass of 34 g/mol.
- Its concentration is 10.5 M.
- Explanation:
- Molartity is the concentration of the solution expressed as number of moles of solute per liters of solution.
- M = number of moles of solute / volume of solution in liters.
How do you know if a solution is concentrated or dilute?
A concentrated solution is one that has a relatively large amount of dissolved solute. A dilute solution is one that has a relatively small amount of dissolved solute. However, these terms are relative, and we need to be able to express concentration in a more exact, quantitative manner.
What is salt solution is the most concentrated?
Explain. Salt solution A contains a concentration of 3 g/L, whereas salt solution B contains 2 g/L. Therefore, solution A is more concentrated than solution B.
Which solution is the most concentrated 0.1 mole?
From the given solutions most concentrated solution is 4th solution. In this the highest amount of solute dissolved in a unit volume is 4.0 mol. Therefore this is the most concentrated solution….
- 0.1 mol/ 0.4 L = 0.25 mol/L.
- 0.2 mol / 0.3 L = 0.67 mol/L.
- 0.3 mol / 0.2 L = 1.5 mol/L.
- 0.4 mol/ 0.1 L = 4.0 mol/L.
What is an example of a concentrated solution?
Common commercial examples of concentrated solutions are hydrochloric acid and sulfuric acid. Hand soap, soft drinks and liquid medicine are concentrated solutions commonly found in the household. Concentrated solutions are best understood relative to dilute solutions. Tap water is an example of dilute solution.
