what did you notice about the way the soil particles sank in the water? how was it different from the way the soil and sand particles sank?

what does the soil look like in the "soil" bottle? how is it different from the soil in the "soil and sand" bottle?

Because a model would make the investigation easier to understand

Sorry i dont understand the question can you rephase it?

Answer:             1.0  × 10⁻⁵ msolution:                     as we know ph is given as,                                    ph  = -log [h⁺]and,                                    [h⁺]  =  10^-ph    (1)putting value of ph in eq. 1,                                    [h⁺]  =  10⁻⁵                                    [h⁺]  =  1.0  × 10⁻⁵ m
