Determina el pH del café cuya concentración de H+ es de 0.00001M
lara31 [8.8K]

Answer:

5

Explanation:

Given parameters:

Hydrogen ion concentration  =  0.00001M

Unknown:

pH of the solution =?

Solution:

The pH is used to estimate the degree of acidity or alkalinity of a solution. To solve for pH of any solution, we use the expression below;

          pH  = -log [H⁺]

[H⁺] is the hydrogen ion concentration

        pH  = -log (1 x 10⁻⁵)

      pH = -(-5) = 5

When the temperature of the air is 25°C, the velocity of a sound wave traveling through the air is approximately
Vitek1552 [10]

Answer ; The correct answer is : 346 m/s .

Sound is a type of longitudinal wave , which is produced when a matter compress or refracts .

Speed of sounds depends on factors like medium , density , temperature etc .

Effect of Temperature on speed of sounds :

When the temperature increases , molecules gains energy and they starts vibrating and with higher temperature vibration becomes fast . So the waves of sounds can travel faster due to faster vibrations . Hence , speed of sounds is directly proportional to the temperature or speed of sounds increases with increase in temperature .

The speed of sounds at 0⁰C is 331 \frac{m}{s}

The relation between speed of sound and temperature is given as :

V = 331 \frac{m}{s}  + ( 0.6 \frac{m}{s- ^0C} * T  )

Given : Temperature = 25 ⁰ C

Plugging values in formula =>

V = 331 \frac{m}{s} + (0.6 \frac{m}{s-^0C}  * 25^0C)

V = 331 \frac{m}{s} + 15 \frac{m}{s}

V =  346 \frac{m}{s}
