The negative logarithm of the hydrogen ion concentration, [H+], a measure of the degree to which a solution is acidic or alkaline. An acid is a substance that can give up a hydrogen ion (H+); a base is a substance that can accept H+. The more acidic a solution the greater the hydrogen ion concentration and the lower the pH; a pH of 7.0 indicates neutrality, a pH of less than 7 indicates acidity, and a pH of more than 7 indicates alkalinity. The pH is used as a measure of whether the body is maintaining a normal acid-base balance.

How would you calculate the unknown concentration of OH given that the solutions reach an equivilance point with their volumes being that NaOH is 12ml and H2C2O4 x H2O is 10ml?
You can't because you do not have a concentration for the acid. The reaction is two alkali reacts with one acid.
What is the weight in grams of a 0.5 N Na2CO3 used in determining the concentration of unknown HCl solution?
A 0.5N Na2CO3 used in determining the concentration of an unknown HCl solution has a weight of 1.06 grams. To find the weight, you need to first find out how many moles there are by calculating molarity times volume.
The absorbance of a solution of NiCl2 of unknown concentration is found to be 0.388 what is the concentration of this soultion?
684
Does changing the concentration of an acid affect the temperature at neutralisation?
Yes, heat of neutralization is directly proportional to the concentration of the acid. the more the concentration the more the heat emitted at the time of neutralization.
Why is 1 stronger than 14 on the pH scale?
Where a liquid is placed on the pH scale depends on the concentration of hydronium in the solution. A pH of 1 indicates the most concentration acid we can find or create and a pH of 14 is the most dilute concentration of hydronium ion we can find or create.
What is the purpose of titration?
The process of Titration is used to determine the unknown concentration of a known reactant, such as acid. It is used industially to find the strength of acid so it can be used for other things.
Why do you do titrations?
A titration is done to determine the concentration of an unknown solution. As an example, consider a concentration unknown acid solution. It can be reacted with a known alkali, and the concentration of the acid can be calculated using the theory of stoichiometry.
What is hypothesis of a acid base titration?
to determine the concentration of the unknown solution and to determine the molar concentration of acetic acid in a sample of vinegar by titrating it with a standard solution of NaOH.
How could determine the concentration of ascorbic acid in an unknown sample?
The concentration of ascorbic acid in an unknown sample can be obtain by conducting a few steps by using the DCPIP test. Firstly, we must obtain the volume (dm ) of the sample solution which are required to turn the DCPIP solution (blue) colour into colourless. After obtaining the volume we use an electronic balance to obtain the mass of the sample solution in gram (g). Then we use the concentration formula of [mass (g) of solute per volume (dm ) of solution] to find out the concentration. Hence. The concentration obtained was the concentration of ascorbic acid.
A student performed a series of titrations to find the concentration of an unknown acid The results of the titrations are shown in the data table What is the mean of this set of data?
0.984 M
What is acidimetry and alkalimetry?
Acidimetry is the process of determining the concentration of an acid in a solution, while alkalimetry is the process of determining the concentration of a base in a solution. Both techniques involve titrating the substance of interest with a standard solution of known concentration to determine the unknown concentration.
Is titration acid or base?
titration is a method by which a solution of known concentration is used to determine the unknown concentration of a second solution. Titration methods are based on reactions that are completed quickly such as the mixing of an acid and base.
Why is a titration performed?
To find the unknown concentration of a sample by using a reagent with a known concentration. ( IE; molarity )
What is titrate?
A Titration is a producers which used to determine the concentration of an acid or base.
What is the purpose of a titration experiment?
To deduce the concentration of a unknown solution from a known solution. Acid/base titration are common.
Where do you find ethanoic acid?
Ethanoic acid, more commonly known as acetic acid, can be found in a 5% concentration in vinegar.
How do you find concentration of an acid from a titration?
use phenol phtalein as an indicator
