Experiment 1: Strong Acid-Base Titrations
Name:__Ashmeen______________         PRA_22_____        Date Sept 21 2021
    Purpose: The purpose of this experiment is to see what the concentration of HCl is by titration HCl with already a known concentration got NaOH
    Theory: Titration is a neutr
alisation technique in which a titrant (a known concentration solution) is introduced into an analyte (unknown solution) until the unknown solution is totally neutralised. It helps in determining the concentration of unknown solution. Phenolphthalein, an indicator is also used in such experiments and is added to solution of unknown concentration to determine its end point. In the performed experiment, the unknown concentration of HCl was determined using NaOH and it was found that average concentration of HCl is 8.215 M.

    Hydrochloric acid
    Physical Properties:
· Colorless liquid
· Pungent, irritating odor
· Comprises of hydrogen chloride gas broken up in water
· Mixes with water
· Produces irritating fumes
Chemical Properties:
· A strong, monoprotic acid
· Dissociates in water to give the hydronium and chloride ions
· Reacts with bases to form chloride salts
    · Erythema and skin irritation
·
· Chemical burns to skin and mucous membranes can arise after long skin exposure
    · Skin corrosion (Category 1B)
· Serious eye damage (Category 1)
· Specific target organ toxicity - single exposure (Category 3)
    · Hydrochloric acid should be stored in a cold, dry, well-ventilated location away from moisture sources.
· Keep oxidising agents, organic compounds, metals, and alkalis aside from different materials.
    In the event of severe skin contact, use water, a disinfecting soap, and an anti-bacterial lotion. Seek medical attention right away. If hydrochloric acid or acidic mists get into your eyes, flush them promptly with plenty of water for at least 15 minutes.
    Sodium Hydroxide
    Physical Properties:
· In its pure form it is a white crystalline solid.
· Odorless
· Soluble in water, glycerol and ethanol
· Rapidly absorbs carbon dioxide and water from the air
· Also exists in the form of a liquid
Chemical Properties:
· Reacts with protic acids to form water and salts
· Has high acidity of 13
· Covalent bond exists between Oxygen and Hydrogen in the hydroxide
    · May be corrosive to metals
· Causes severe skin burns and eye damage
    · Skin corrosion/irritation, Category 1A H314 Causes severe skin burns and eye damage.
· Serious eye damage/eye irritation, Category 1 H318 Causes serious eye damage.
· Hazardous to the aquatic environment — Acute Hazard, Category 3 H402 Harmful to aquatic life
    · Avoid its contact with eyes, skin, and clothing.
· Wear protective eye-ware and gloves.
· To avoid freezing and caustic deposition, it should...
