Why Some Strong Acids are LESS Corrosive than Weak Acids?

Hi Students,

Most of the the students are confused confused in the above mentioned questions. They always thought that weak acids must not be corrosive. This is a wrong concept. Let us revise again the topics of Acids and Bases.

Strong Acids
Strong acids completely dissociate in water, forming H+ and an anion.
There are six strong acids:
  1. HCl - hydrochloric acid
  2. HNO3 - nitric acid
  3. H2SO4 - sulfuric acid
  4. HBr - hydrobromic acid
  5. HI - hydroiodic acid
  6. HClO4 - perchloric acid

Weak Acids
A weak acid only partially dissociates in water to give H+ and the anion. Examples of weak acids include hydrofluoric acid, HF, and acetic acid, CH3COOH.

Strong is Different from Corrosive

Corrosiveness is related to the negatively-charged part of the acid. Hydrofluoric acid (HF), for example, is so corrosve it dissolves glass. The fluoride ion attacks the silicon atom in silica glass while the proton is interacting with oxygen. Even though it is highly corrosive, hydrofluoric acid is not considered to be a strong acid because it does not completely dissociate in water.

Great Law of Attraction Affirmations

Affirmations, really, are simple. They are you being in conscious control of your thoughts. They are short, powerful statements. When you say them or think them or even hear them, they become the thoughts that create your reality. Affirmations, then, are your conscious thoughts.

Research has shown that we have between 45,000 and 51,000 thoughts a day. That’s about 150 to 300 thoughts a minute. Research has also shown that for most people 80% of those thoughts are negative.

Now, we have been taught to think that most of these 51,000 thoughts are “sub-conscious” thoughts meaning that they are below our conscious awareness level. Affirmations actually make your sub-conscious thoughts conscious. Affirmations make you consciously aware of your thoughts. When you start making conscious positive thoughts, you actually become more aware of the negative thoughts that are always threatening to take over.

Affirmations can be further divided into different catagories. I think the most popular one should be Money Affirmation. Let's take a look on some examples.

Money Affirmation 1: I create my own reality and I have unlimited prosperity.
Money Affirmation 2: Financial abundance comes to me easily.
Money Affirmation 3: Large amounts of money come to me quickly and easily from multitudes of sources now.
Money Affirmation 4: I always have abundant amounts of money; more coming in than going out.
Money Affirmation 5: Unlimited possibilities and resources reveal themselves to me now.
Money Affirmation 6: I am comfortable having money.
Money Affirmation 7: Money is good and I deserve money.
Money Affirmation 8: I feel successful and I am successful.
Money Affirmation 9: I have more money than I ever dreamed was possible.
Money Affirmation 10: I expect only the best from my financial situation and the Universe provides just that or better.
Money Affirmation 11: I have a constant stream of money abundance in my life.
Money Affirmation 12: I have my ideal life.
Money Affirmation 13: I am able to think and feel in unlimited ways.
Money Affirmation 14: I have all the answers within myself and I implement them.
Money Affirmation 15: I am financially free.

The Power of Determination

"Everybody here has the ability to do absolutely anything I do and much more beyond. Some of you will and some of you won't. For the ones who won't, it will be because you get in your own way, not because the world doesn't allow you" ~~ Warrent Buffett.

翻译:
每个人都有能力办到我所能够办到的事情,也许比我更多。有些人可以,然而也有些人无法做到。那些无法办到的,是因为你不愿意改变想法,而不是世界不允许你成功。”~~股神巴菲特
