Hard water at home contains dissolved ions (ex. Ca2+ & Mg2+) that react with soap to form a nasty gray substance. Because this gray stuff would ruin your clothes, most laundry detergents add ingredients that combine with the Ca2+ and Mg2+ ions to form insoluble precipitates that are easily washed away with the dirty water. a.) NaCl b.) Na2CO3 c.) NaNO3 d.) KI e.) Pb(OH)2 i got b but is that right?
