What value is ued to express the acidity or bacity of a solution called?
The acidity or basicity are expressed by pH (the negative logarithm of the activity of hydronium ion).
What do the numbers on the pH scale say about the solution?
acidic (lower than 7) neutral (7) and basic (higher than 7)
What will happen to the hydronium ion concentration and pH of water if hydronium acid is added?
Hydrogen ions will form and the pH of the water will increase.
The concentration of an acid or base refers to?
False
What dos the pH scale actually measure?
pH is a measure of the acidity of the solution. It describes the concentration of H+ or H3O+ ions in a solution. pH= -log10[H+]. Therefore, the lower the pH, the higher the concentration of hydrogen atoms and the more acidic the solution.
What ions are measured with a pH scale to determine the acidity of a solution?
The inverse logarithm of the concentration of hydronium ions in a water solution; basicaly, how acidic a solution is.
If the pH of a solution decreases below 7.0 1. the acidity of the solution increases 2. the acidity of the solution decreases 3. the hydronium ion or hydrogen ion concentration increases 4. the hydron?
You guys are too smart.
What is the measure of acidity in terms of hydronium ion concentration?
pH is a measure of the activity of hydroxide (OH-) and hydronium (H3O+) in aqueous solution. Acidic solutions have greater numbers of reactive hydronium ions. Basic solutions have more hydroxide ions and less reactive hydronium ions.
What the pH number of an indicator for the concentration of?
The pH value is an indication of the acidity/alkalinity of a solution. More precisely, the pH value is a representation of the concentration of hydrogen cations (hydronium ions) in a solution.
What value is ued to express the acidity or bacity of a solution called?
The acidity or basicity are expressed by pH (the negative logarithm of the activity of hydronium ion).
What is an acidity function?
An acidity function is the relationship between the acidity of a solution and the concentration of its solute.
What is acidity function?
An acidity function is the relationship between the acidity of a solution and the concentration of its solute.
What value is used to express the acidity or icity of a solution called?
The acidity and the basicity are expressed by pH (the negative logarithm of the hydronium ion activity).
Does The acidity of a solution reflects the free hydrogen ions in the solution?
Yes, free H+ concentration is the only measure of acidity.
The acidity of a solution reflects the free hydrogen ions in the solution?
Yes, free H+ concentration is the only measure of acidity.
What is meant by the pH of a solution?
The value for pH (classically 0 to 14) is the measure of how acidic or basic a solution is.The abbreviation is from the term power or potential of hydrogen, giving the relative molar concentration of hydronium ions (H3O+ i.e. hydrogen ions in solution).
What do the numbers on the pH scale say about the solution?
acidic (lower than 7) neutral (7) and basic (higher than 7)
