COMMON LABORATORY APPARATUS EQPT, AND THEIR USE

Question 1

It is used to broadly test whether a solution is acidic or basic and comes in 3 types- red, blue, and neutral.

Answer 1

Litmus Paper

Question 1

Are pieces of paper that change color depending on the pH – the acidity or alkalinity – of a liquid.

Answer 1

pH Strips

Question 2

These are most often found in a laboratory or places where extreme sensitivity is needed for the weighing of items.

Answer 2

Analytical Balance

Question 3

This is another balance used primarily in a laboratory setting. They usually can measure objects weighing around 150–5000 g.

Answer 3

Top-Loading Balance

Question 4

This type of laboratory balance is less sensitive than a top-loading balance. They are often used in a classroom situation because of ease of use, durability and cost.

Answer 4

Triple-Beam Balance

Question 5

It is a cylindrical glass or plastic vessel used for holding liquids.

Answer 5

Beaker

Question 6

Used to measure temperature in Celsius.

Answer 6

Thermometer

Question 6

Used to pick up beakers.

Answer 6

Question 7

is a cone-shaped container with neck, so you can hold the flask or attach a clamp or use a stopper.

Answer 7

Erlenmeyer flask

Question 8

It is characterized by having a bulb and a long neck.

Answer 8

Volumetric flask

Question 9

It is a relatively slim glass or plastic cylinder used specifically for calibrating beakers or measuring a liquid’s volume. Come in a variety of sizes such as 10 ml, 25 ml, 50 ml,100 ml, 500 ml and 1,000 ml.

Answer 9

Graduated cylinder

Question 10

It is a cylindrical, laboratory glass apparatus that is used to measure the volume of liquids.

Answer 10

Burette

Question 10

It is a device with a piston-driven air displacement mechanism used to transport a given volume of liquid mostly in the laboratory.

Answer 10
