Frequently Asked Questions about Milk

Is Milk an Acid or Base?

Milk is slightly acidic. As its pH is very near to 7, it is often considered neutral. However, it mostly isn’t completely neutral because of the presence of lactic acid in milk. This acidity decreases the pH of milk over time and makes the milk more acidic and sour.

Is Milk a Strong or Weak Acid/Base?

Fresh milk is slightly acidic but isn’t a strong acid. Depending on freshness and source, the acidity differs. The lactobacillus bacteria makes lactic acid in milk and increases the acidity over time. However, lactic acid being a weak acid itself, can’t make milk show strong acidic properties.

What is Milk commonly used for?

Milk is a vital part of the human diet. It is  one of the major sources of protein and fat. It also has other important nutrients like calcium, vitamin D, Vitamin B etc. Cream, butter, yogurt, cheese and many delicious meals or desserts are made using milk.

How to Find and Choose a Chemistry Tutor

Instructor Reputation

In addition to finding a teacher with good ratings, consider several factors when choosing your chemistry teachers, such as the location, teacher punctuality, diversity of teaching styles, and personality fit. The cost of chemistry lessons often aligns with the teacher’s expertise.

Experience and Specialization of the Teacher

Chemistry teachers sometimes prefer one topic over another, so take advantage of the tutor interview process to understand if they are a good fit. You will want to ensure to find the right fit and price ranges. Just because a teacher is good at chemistry, this is no indication of their ability to teach you or your child.

Virtual VS On-Site Chemistry Lessons

Today, most chemistry lessons occur over online video. However, depending on the lesson, including organic chemistry, inorganic chemistry, chemical reactions, quantum mechanics, inorganic compounds, atomic structure, organic reactions, etc., many teachers are willing to provide safe sessions in person if they are located nearby.
