A. List the potential acute health effects.
AleksandrR [38]

When we handle chemical substances we must be very careful because they can put our:

  • Physical integrity.
  • Health
  • Life at risk.

<h3>What is a chemical?</h3>

A chemical substance is a chemical compound resulting from the union of two or more chemical elements. Compounds have different uses depending on their properties. However, some can be harmful and life-threatening to humans.

<h3>Potential acute effects.</h3>

The potential acute effects of some compounds may be related to skin contact causing:

  • Inflammation
  • Redness
  • Rash
  • Burns
  • Dry
  • Among other.

On the other hand, the chronic effects of chemical compounds can be:

  • Diseases in the central nervous system.
  • Respiratory diseases.
  • Skin diseases.
  • Degenerative diseases of the bone system.

<h3>What to do when a chemical is ingested?</h3>

There are a large number of chemical substances and each one has different properties. Therefore, it is very difficult to generalize about a treatment in case of ingestion. What must be done is to know the level of risk of the substance that is being handled and avoid ingesting it at all costs. However, if it is ingested, go to the emergency room.

<h3>Product flammability</h3>

Not all chemical compounds have the same flammable response to fire. Due to the above, it is necessary to identify if the substance that we are handling is highly or slightly flammable, for this we can consult the manual of the substance or the label of its packaging.

<h3>3 Chemical that produces a potentially dangerous reaction with hydrochloric acid.</h3>

According to some studies and the hydrochloric acid safety data sheet, it can have dangerous reactions with:

  • Reacts violently with water.
  • Gives off hydrogen in reaction with metals.
  • Keep away from strong bases.

<h3>How to handle small spills?</h3>
  • Contain the spill.
  • Soak up with inert absorbent material.
  • Prevent the product from entering the sewage system.
  • Keep in suitable, closed containers for disposal.

<h3>Personal Protection</h3>

When we handle chemical substances we are facing a potential risk. Due to the above, protocols have been developed for its handling, which include the use of protection elements such as:

  • Gloves
  • Glasses
  • Helmet
  • Mask
  • Boots
  • Special suit.
  • Among others.

<span>HCl(aq)+CH3NO2(aq)⇄CH3NH3+(aq)+CL-(aq) Given that the concentrations of the HCl and methyamine are equal, so at the equivalence point the volume is doubled. The resulting concentration of CH3NH3+ is 0.095M CH3NH3+(aq)⇄H+(aq)+CH3NH2(aq) I 0.095 0 0 C -x +x +x E 0.095-x x x Ka=x^2/0.095-x Ka=1.0x10^-14/5.0x10^-4 =2.0x10^-11 x^2/0.095-x=2.0x10^-11 x=1.38x10^-6 pH=-log(1.38x10^-6) =5.9</span>
