Gold is a mixture Becasue it contains more than one element
Explanation:
Bases have a slippery feel when touched but acids do not have a slippery feel.
- An acid is a substance that interacts with water to produce excess hydroxonium ions, H₃O⁺ in an aqueous solution. Here are some of its properties:
- Their dilute solutions have a sour taste.
- They have a burning effect on the skin and are highly corrosive on metals.
- They have the ability to change the colors of indicators.
- They react with bases to form salt and water only.
Examples of acids are:
Hydrochloric acid HCl
Tetraoxosulphate (VI ) acid H₂SO₄
- A base is a substance that interacts with water to produce excess hydroxide ions, OH⁻ in an aqueous solution.
- They typically have a bitter taste.
- They have a soapy feel
- They are electrolytes
- They also change the color of indicators
Examples are:
Potassium hydroxide KOH
Sodium hydroxide NaOH

Explanation:
1 tablespoon of baking soda
1 1/2 cups of vinegar
its a dressing but salad is related to a maynoise or a sauce
The concentration of each of the individual ions in a 0750 M Ba(OH)2 solution is
[Ba2+] = 0.750 M
[OH-]= 1.50 M
<h3>
calculation</h3>
write the equation for dissociation
that is Ba(OH)2 (s)→ Ba2+(aq) + 2OH-(aq)
by use of mole ratio of Ba(OH)2 : Ba2+ which is 1: 1 the concentration of Ba2+ is therefore= 0.750M
by use of mole ratio of Ba(OH)2 : OH- which is 1:2 the concentration of OH- =0.750 M x2/1=1.50 M
