Enaltec Labs Interview Questions and Answers for Experienced

pH is a measure of acidity or alkalinity in a solution, ranging from 0 to 14.

• pH stands for 'potential of hydrogen'

• It measures the concentration of hydrogen ions in a solution

• A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline

• The pH scale is logarithmic, meaning each unit represents a tenfold difference in acidity or alkalinity

• Examples: lemon juice has a pH of around 2, water has a pH of 7, and b...read more

Titrations is a laboratory technique used to determine the concentration of a substance in a solution.

• It involves adding a known amount of a solution of known concentration to a solution of unknown concentration until a reaction is complete.

• The point at which the reaction is complete is called the endpoint.

• The amount of the known solution added is used to calculate the concentration of the unknown solution.

• Titrations c...read more

Acid and base are chemical substances that have opposite properties and can react with each other.

• Acid: hydrochloric acid (HCl), sulfuric acid (H2SO4), acetic acid (CH3COOH)

• Base: sodium hydroxide (NaOH), potassium hydroxide (KOH), calcium hydroxide (Ca(OH)2)

Deviation refers to a departure or divergence from a standard or expected course or outcome.

• Deviation is a variation or deviation from a specified norm, standard, or expectation.

• It can occur in various contexts such as manufacturing, quality control, and project management.

• Examples of deviation include a product not meeting the required specifications, a process not following the defined procedures, or a project not ad...read more

An incident is an unplanned event that disrupts normal operations and requires immediate action.

• Incidents can range from minor issues to major disasters.

• They can be caused by human error, equipment failure, or natural disasters.

• Examples of incidents include power outages, system crashes, and security breaches.

• Incidents must be reported and investigated to prevent future occurrences.

• Effective incident management involve...read more

CAPA stands for Corrective and Preventive Action. It is a systematic approach to identify, investigate, and resolve issues to prevent their recurrence.

• CAPA is a quality management process used to address and rectify non-conformities and prevent their recurrence.

• It involves identifying the root cause of a problem, implementing corrective actions to address the immediate issue, and preventive actions to prevent similar i...read more

Types of reactions include acid-base, redox, precipitation, and gas-forming reactions. Proper handling of acids is crucial to prevent accidents. Gases produced in reactions can be toxic or flammable.

• Types of reactions: acid-base, redox, precipitation, gas-forming

• Proper acid handling: use appropriate protective equipment, work in a well-ventilated area

• Gases produced in reactions: can be toxic or flammable, handle with c...read more
