Answer : The correct option is, (B) NaOH

Explanation :

Indicators : It is a substance that gives the visible sign by the color change of the chemical species like an acid or a base.

Universal Indicator : It changes color when mixed with an acid or base.

Universal Indicator turns red when it is added to a strong acid, it turns blue or purple when it is added to a strong base and it turns a yellowish-green when it is added to a neutral solution.

The pH range is, 1 to 14.

When the value of pH is less than 7 then the solution is acidic.

When the value of pH is more than 7 then the solution is basic.

When the value of pH is equal to 7 then the solution is neutral.

According to the pH chart, HCl is a strong acid whose pH is 1, saliva is also an acid whose pH is less than 7 that is 6.8. NaOH is a strong base whose pH is 14. The blood is slight basic in nature and the pH of blood is 7.4.

Hence, the strongest base is, (B) NaOH

Cuántos mililitros de agua hay en 3 litros de una botella de naranjas y las solucion tiene una concentracion de 20% v/v
sertanlavr [38]

Respuesta:

2400 mL

Explicación:

Paso 1: Información dada

  • Volumen de solución: 3 L (3000 mL)
  • Concentración de naranja: 20 % v/v

Paso 2: Calcular el volumen de naranja

La concentración de naranja es de 20 % v/v, es decir, cada 100 mL de solución hay 20 mL de naranja.

3000 mL Sol × 20 mL Naranja/100 mL Solución = 600 mL Naranja

Paso 3: Calcular el volumn de agua

El volumen de soluciónes igual a la suma de los volúmenes de naranja y agua.

VSolución = VNaranja + VAgua

VAgua = VSolución - VNaranja

VAgua = 3000 mL - 600 mL = 2400 mL
