When salt and sugar is mixed together it therefore to be regarded as a homogeneous substance because the components cannot be seen. This is my little observation and results 

Homogeneous mixture: Homo means the same while Geneuos means to see. And mixture to combine. So when join together, it a give a single meaning. Therefore, it is the mixture of which the same substance in a medium can see but a mixture of different substance in a medium cannot be seen. Ex. sugar dissolved in water, we cannot see it.

Salt dissolved in water.
We cannot see the salt in the water,the two components are mixed uniformly so it is a homogeneous mixture.

<h2>Homogeneous Mixtures</h2>
<p>A <strong>homogeneous</strong> mixture has a definite composition, and specific properties. In a homogeneous mixture, the different parts cannot be seen. A <a data-lesson="dilute-and-concentrated-solutions" data-subject="chemistry" data-tutorial="acid-base-redox-reactions" href="https://app.ulearngo.com/chemistry/acid-base-redox-reactions/dilute-and-concentrated-solutions">solution</a> of salt dissolved in water is an example of a homogeneous mixture. When the salt dissolves, it spreads evenly through the water so that all parts of the solution are the same, and you can no longer see the salt as being separate from the water. Think also of coffee without milk. The air we breathe is another example of a homogeneous mixture since it is made up of different <a data-lesson="introducing-gases" data-subject="chemistry" data-tutorial="gases" href="https://app.ulearngo.com/chemistry/gases/introducing-gases">gases</a> which are in a constant ratio, and which can't be visually distinguished from each other (i.e. you can't see the different components).</p>

<h3>Did You Know?</h3>
<p>An <strong>alloy</strong> is a homogeneous mixture of two or more elements, at least one of which is a metal, where the resulting material has metallic properties. For example steel is an alloy made up mainly from iron with a small amount of <a data-lesson="carbon" data-subject="chemistry" data-tutorial="metals-metalloids-nonmetals" href="https://app.ulearngo.com/chemistry/metals-metalloids-nonmetals/carbon">carbon</a> (to make it harder), manganese (to make it strong) and chromium (to prevent rusting).</p>

<h3>Definition: Homogeneous mixture</h3>

<p>A homogeneous mixture is one that is uniform, and where the different components of the mixture cannot be seen.</p>

<h2>Example: Mixtures</h2>
<div class="ns-school-defn">
<h3>Question</h3>
<div>
<p>For each of the following mixtures state whether it is a homogeneous or a heterogeneous mixture:</p>
<ol>
<li>
<p>sugar dissolved in water</p>
</li>
<li>
<p>flour and iron filings (small pieces of iron)</p>
</li>
</ol>
</div>
<div>
<h3>Step 1: Look at the definition</h3>
<p>We first look at the definition of a heterogeneous and homogeneous mixture.</p>
</div>
<div>
<h3>Step 2: Decide whether or not you can see the components</h3>
<ol>
<li>
<p>We cannot see the sugar in the water.</p>
</li>
<li>
<p>We are able to make out the pieces of iron in the flour.</p>
</li>
</ol>
</div>
<div>
<h3>Step 3: Decide whether or not the components are mixed uniformly</h3>
<ol>
<li>
<p>The two components are mixed uniformly.</p>
</li>
<li>
<p>In this mixture there may be places where there are a lot of iron filings and places where there is more flour, so it is not uniformly mixed.</p>
</li>
</ol>
</div>
<div>
<h3>Step 4: Give the final answer</h3>
<ol>
<li>
<p>Homogeneous mixture.</p>
</li>
<li>
<p>Heterogeneous mixture.</p>
</li>
</ol>

<h2>Optional Activity: Making mixtures</h2>
<div class="ns-school-defn">
<p>Make mixtures of <a data-lesson="mixtures" data-subject="chemistry" data-tutorial="classification-of-matter" href="https://app.ulearngo.com/chemistry/classification-of-matter/mixtures">sand</a> and water, potassium dichromate and water, iodine and ethanol, iodine and water.

Homogeneous Mixtures

Chemistry generally explores the substances of which matter is composed, the investigation of their properties and reactions, and the use of such reactions to form new substances. 

Chemistry

Explore the arrangement of elements and learn about materials, mixtures, pure substances, and separation techniques, including chemical formulae and important concepts such as periods in the periodic table and chemical properties of groups.
