| 47 When the pH of an aqueous solution is changed from 1 to 2, the concentration of hydronium ions in the solution is (1) decreased by a factor of 2 (2) decreased by a factor of 10 (3) increased by a factor of 2 (4) increased by a factor or 10 | 2 | link |
When a pH of an aqueous solution is changed from 1 to 2 the concentration of hydronium ions in the solution is?
Answer Expert Verified. The answer is (2) decreased by a factor of 10. The relationship between pH and concentration of hydronium ions is pH=-lg[H+]. So pH increase because of concentration of H+ decrease.
When the pH of a solution is changed from 5 to 3?
By dividing the equation 1 and 2 we get the ratio of the hydronium ion concentration. From this we conclude that when the pH of a solution changes from a pH of 5 to a pH of 3, the hydronium ion concentration is 100 times the original content. Hence, the correct option is, (D) 100 times the original content.
When the pH of a solution is changed from 4 to 3 what happened to the hydronium ion concentration of the solution?
Answer Expert Verified When the pH of a solution is changed from 4 to 3, the hydronium ions increases by a factor of 10. pH is a scale used to measure the acidity or alkalinity of an aqueous solution. It can be used to calculate the amount of hydronium ions in the solution. It is expressed as: pH = -log [H+].
Is pH dependent on concentration?
The pH scale is logarithmic and inversely indicates the concentration of hydrogen ions in the solution. The neutral value of the pH depends on the temperature, being lower than 7 if the temperature increases. The pH value can be less than 0 for very strong acids, or greater than 14 for very strong bases.
Why does pH of water decreases with temperature?
*pH decreases with increase in temperature. In the case of pure water, there are always the same concentration of hydrogen ions and hydroxide ions and hence, the water is still neutral (even if its pH changes).
Is blood an alkali?
Your blood has a normal pH range of 7.35 to 7.45. This means that blood is naturally slightly alkaline or basic. In comparison, your stomach acid has a pH of around 1.5 to 3.5. This makes it acidic.
