Ph meter
The purpose of the electronic computer was to make conversion of raw data into useful information easier. Before the electronic computer, people used mechanical computers like the Abacus.
The Berlin wall was once used to divide Berlin. It was built by the German Democratic Republic, frequently called East Germany. The wall was torn down in 1990.
It was an early form of electronic communication where Morse Code was used to send messages by wire.
Conical springs are most often used for "telescoping" of a rod and a bore. They are used in a wide variety of industries, and the exact use will determine the manufacturing requirements of the spring, which will determine the ultimate use for which a particular spring can be used.
Vacuum tubes were used back in the 19th century and mid-20th century for a number of things. At first they were used just in scientific areas, but then they were used as electronic amplifiers. They were eventually used in the first computers.

they are used to, determine the pH of a solution. ~natalia !
spectrophotometer is used to determine the concentration of solution by means of reflectance or transmittance by the solution
A solution of potassium bismuth iodide. It is used to determine the presence of alkaloids.
Litmus paper can be used to determine if a solution is acidic or basic
A standard solution is a solution of known concentration used in titration to determine the concentration of an unknown solution. It is usually added to the unknown solution until a desired reaction is completed, allowing the concentration of the unknown solution to be calculated based on the volume of standard solution used.
Iodine Solution is used to determine whether starch is present.
Litmus solution is used to test whether a substance is acidic or basic. It turns red in an acidic solution and blue in a basic solution. It is commonly used in science laboratories and in various industrial applications to determine the pH of a solution.
Titration is important as it can determine the concentration of a substance accurately. It is commonly used in chemistry to analyze the properties of a solution. Titration also helps in identifying unknown substances by reacting them with a known solution.
Titration is a laboratory method used to determine the concentration of a solution by reacting it with a solution of known concentration. It is commonly used to measure the concentration of acids and bases, as well as other substances in solution.
Double titration is a titration method used to determine the concentration of a solution by performing two successive titrations. In the first titration, a known concentration of a standard solution is used to titrate the unknown solution. In the second titration, a different standard solution is titrated with the excess volume from the first titration to determine its concentration.
