If the pH of a solution is decreased from pH 8 to pH 6 it means that the concentration of hydrogen ions in the solution has been increased while the concentration of OH ions have been decreased.

<h2>Further Explanation: </h2><h3>pH and pOH </h3>
  • pH and pOH measures the acidity or alkalinity of a substance.
  • pH is the measure hydrogen ion concentration in a substance while pOH measures the concentration of hydroxyl ions.
<h3>Acids and bases </h3><h3>Acids </h3>
  • Acids are substances that react with bases to form salt and water as the only products.
  • Acids have a pH less than 7, with strong acids having a pH range of 1-3 while weak acids have a pH range of 4-6.
  • The pOH of acids on the other hand is greater than 7.
<h3>Bases</h3>
  • Bases are substances that react with acids to form salt and water as the only product.
  • Bases have a pH greater than 7, with strong bases having a pH range of 12-14 and weak bases having a pH range of 8-11.
  • Bases have a pOH less than 7.
<h3>Calculation of pH and pOH </h3>
  • pH is calculated as the negative logarithm of hydrogen ion concentration.

That is;

pH = -Log [H+]

  • pOH on the other hand is calculated as the negative logarithm of hydroxyl ion concentration.

That is;

pOH =-Log[OH-]

Additionally;

pH + pOH = 14

Explanation:

Relation between pH and concentration of hydrogen ions is as follows.

                  pH = -log [H^{+}]

So, it means that an increase in the value of pH will show that there occurs a decrease in concentration of hydrogen ions.

Therefore, the solution becomes basic in nature.

On the other hand, a decrease in the value of pH will show that there occurs an increase in the concentration of hydrogen ions.

Therefore, the solution becomes more acidic in nature.

Hence, if the pH of a solution is decreased from pH 8 to pH 6 it means that the concentration of hydrogen ions has increased in the solution.

A certain isotope has 53 protons 78 neutrons and 53 electrons. What is its atomic number? What is the mass number of this atom?
statuscvo [17]

Answer:

  1. 53 protons
  2. 131g
  3. Iodine
  4. Halogens

Explanation:

atomic no. = no. of protons

= 53 proton

mass = no. of protons + no. of

neutrons

= 53 + 78

= 131

professor190 [17]
In an exothermic reaction, the water will increase in temperature in a calorimeter. An exothermic reaction is a reaction where heat is one of the products or heat is being released from it which will cause for the temperature inside the calorimeter to increase.
