What is the result in the solution with pH equals to seven?
At pH 7, the substance or solution is at neutral and means that the concentration of H+ and OH- ion is the same. If pH < 7, the solution is acidic.
Which of the given two solutions have the more concentration of H+ ions solution with pH 4 or solution with pH 10?
Therefore, pH =4 have more H⁺ ions concentration.
Why we say that lower the pH than 7 more acidic is the solution whereas greater the pH than 7 More basic is the solution?
A pH value less then 7 indicates an acidic solution, while greater than 7 indicates a basic solution. Therefore, the solution with pH=6 is acidic and has more hydrogen ion concentration than the solution of pH=8 which is basic.
What is the relationship between a solution of pH1 and one of pH3?
As can be seen in the table, a change in pH value of 1 unit is equivalent to a ten-fold change in hydrogen ion concentration. Example: How many times greater is the hydrogen ion concentration of a solution with pH=1 than a solution with pH=3? Therefore pH1 has a hydrogen ion concentration 100 times greater than pH3.
Which solution has more H+ ions?
Acidic solutions
Neutral solutions have an equal number of H+ ions and OH- ions. Acidic solutions have a higher H+ concentration. An acid is a substance that increases H+ when dissolved in water.
Which of the given two solutions have the more concentration of H+ ions?
acidic solution
An acidic solution has more number of H + ions, since acids dissociate to produce H + ions. Hence, A will have more concentration of H + ions.
Which is more acidic a solution of pH 2 or a solution of pH 6?
A solution with a pH of 2 is more acidic than a solution with a pH of 6, because an acidic solution has a pH value of less than 7. As the pH value decreases from 7, the acidity of a solution increases because there is an increase in the concentration of hydrogen ions (H+ ions).
What happens when a solution of an acid is mixed with a solution of a base in a test tube?
When an acid is mixed with a base, neutralization reaction takes place where salt and water are formed. This is an exothermic reaction i.e. heat is evolved in the process.
