What is the pH of a solution of 1.0 x 10 -3 M H30?
pH is the negative log of the hydrogen ion concentrationthe hydrogen ion concentration is .001 in this instance thereforepH = -log[.001] = 3
What is the pH when the hydrogen ion concentration is 2.0 x 10-3 M?
- log(2.0 X 10 -3 M) = 2.7 pH ======
What does the term pH mean?
pH is the measure of the acidity or alkalinity pH means the power of Hydrogen. It is 'minus the decimal logarithm of the hydrogen ion activity in an aqueous solution'. The term was coined by Sørensen, it measures the alkalinity or acidity of a liquid. pH is a measure of the concentration of hydrogen ions [H+] in a solution. The concentration of the hydrogen ions is measured in Molarity (M), or moles of H+ ions per liter of solution. The pH is then expressed as the negative log (base ten) of the hydrogen ion concentration. pH = -log[H+] For example, if a solution has a hydrogen ion concentration of 4.75 x 10-5 M (or 4.75 x 10-5 moles of H+ ions per liter of solution), then the pH of the solution would be -log[4.75 x 10-5] = 4.323 pH is generally given on a scale from 0-14, with 0 being the most acidic solution (like HCl) and 14 being the most basic solution (for example, NaOH.), although extreme values may sometimes fall outside that range. Pure water has a pH of 7 because its H+ concentration is 1.0 x 10-7 M -log[1.0 x 10-7] = 7
What is 10 to ninth per liter?
"10 to the ninth per liter," or (10^9) per liter, typically refers to a concentration of a substance, indicating that there are one billion (1,000,000,000) units of that substance in one liter of solution. This unit is often used in fields like chemistry and biology, particularly when measuring concentrations of cells, molecules, or other entities in a liquid medium.
How do you convert 10 mg to 10 ml?
You divide the mass of a substance by its density.
