The concentration of hydroxide ions is less than the concentration of hydronium ions for acidic solutions. true false

Answer : The given statement is true.

Explanation :

pH : It is defined as the negative logarithm of hydrogen ion or hydronium ion concentration.

Mathematically,

As per question, the concentration of hydroxide ions is less than the concentration of hydronium ions then its pH become less than 7 and the solution will be acidic.

Hence, the given statement is true.

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer
