Answer:
Acidic inorganic salts, such as AMMONIUM LAURYL SULFATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases.

Answer:
Q = 25.6 j
Explanation:
Given data:
Energy needed= ?
Mass of lead = 10.0 g
Initial temperature = 30 °C
Final temperature = 50°C
Cp = 0.128 j/g.°C
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 50°C - 30°C
ΔT = 20°C
Now we will put the values in formula.
Q = 10 g × 0.128 j/g.°C × 20°C
Q = 25.6 j
