The primary reason behind the formation of the toxic foam is high phosphate content in the wastewater because of detergents used in dyeing industries, dhobi ghats and households.

(ii) Which of the following statements is correct for the water with detergents dissolved in it
1 Low concentration of hydroxide ion (OH⁻) and high concentration of hydronium ion (H₃O⁺)  
2 High concentration of hydroxide ion (OH⁻) and low concentration of hydronium ion (H₃O⁺)  
3 High concentration of hydroxide ion (OH⁻) as well as hydronium ion (H₃O⁺)  
4 Equal concentration of both hydroxide ion (OH⁻) and hydronium ion (H₃O⁺)
