We should expect that many solutions contain species that fall into one of these categories or both. One way to determine the acidity of a solution is to measure its pH with a pH meter. The pH is a measure of acidity and represents a measure of the concentration of hydronium ions (H3O+...
Photo: How do you measure the pH of soils on Mars? Simple! You build a pH meter into a robotic space probe. The Mars Phoenix Lander space probe (left) used this built-in, mini chemical laboratory (right) to measure different aspects of the Martian soil, including acidity and metal ...

Titration is a method to determine the concentration of a substance. A known amount of the solution is pipetted into a flask. A pipet is a long tube that can measure volume very accurately. A solution of known concentration which reacts with the first substance is added using another highly...
number, the more acidic a substance is. Water, for example, has a pH of 7 and is considered neutral (neither acid nor base). You can determine the pH of a chemical by using a pH indicator strip and checking the strip's color to a pH chart. For fun, measure the pH of lemon ...
The Henderson-Hasselbalch equation solves for the pH of a solution using pKa, which is the negative log of the acid dissociation constant. This value is an equilibrium constant for the reaction of {eq}HA \rightleftharpoons A^- + H^+ {/eq}, which is a measure of how strong an acid ...
pH: pH is commonly used to express how basic or acidic a compound is on a scale of 0 to 14. 14 is very basic and 0 is very acidic, with 7 representing a neutral compound. It is a measure of the amount of free hydrogen in a solution. ...
Introduction to pH Measurement pH meter is an instrument used to measure acidity or alkalinity of a solution - also know as pH. pH is the unit of measure that describes the degree of acidity or alkalinity. It is measured on a scale of 0 to 14. The quantitative information provided by...
Below, we explain alkaline versus acidic pH levels, how to know if you are acidic or not, pH imbalance symptoms and ways to check if your body fluids are alkaline or acidic. Video of the Day What Is Body pH? Your body's pH is a measure of how much acidity or alkalinity is in your...
Systems that measure hand and finger geometry use adigital cameraandlight. To use one, you simply place your hand on a flat surface, aligning your fingers against several pegs to ensure an accurate reading. Then, a camera takes one or more pictures of your hand and the shadow it casts. ...
